Kink DIY – 3D Printing

This is a new one for me, but using a 3D printer to conjure new pervertables out of thin air is extremely enjoyable.

I’m going to add a couple of links and files here but this may end up growing over time I as I think it opens up whole new opportunities for fun!

S10 gas mask blackout caps

I have a pair of original flash lenses with some foamboard inserts for complete blackout, but I find they’re extremely tricky to get on during a scene – you end up squishing the poor sub’s face!

So these are great, they click on from the outside but don’t need a huge amount of force to do so and are a lot cheaper to print than buying original parts. I didn’t need to modify them at all, just print away.

Gas mask restrictor valve

This is an adjustable inlet valve – obviously not something to use on your own. I’ve seen a few of these for sale that set you back like £20. I took a design and modified it so that it’s a lot easier to use with slippery or gloved hands, and doesn’t need any supports adding for printing.

It’s printed in two parts, the main body and then the inlet portion. They just press-snap together when you’re done. I used 40% infill for the thinner valve portion, 20% for the main body.

The STLs are here:

NATO gas mask to anaesthetic connector

This is used in my poppers machine, as it has a 4.9mm hole in the side as the injection port.


Fetishak Backpack Gas Mask Hose Connector

Bit of a niche one this, but as the company no longer exists, if you’ve broken yours these may help you out.

Frustrations in chastity

Although I have now received the belt back, I am reinstating this post because I have heard from several others with similar stories so I am concerned my experience was not a one off.

I want to be clear upfront about the purpose of writing this up here, and that is to document the extraordinary number of attempts to resolve this issue in private. I fully and absolutely understand the challenges the last year has brought, particularly to small manufacturers. If I were told that this repair was going to have taken a year, I still would have done it, but after many emails and twitter messages I felt forced into going public.

With the pre-amble out the way then, what’s the problem? In 2020, after a couple of years at trying to get in touch with Carrara, I managed to get an online appointment with them to arrange an adjustment to the size of my belt.

What follows is a record of all my interactions since then trying to get it back.

26/5/2020 – Initial online chat and measuring, I am told it is not very complicated and will “only take a few days”.
5/6/2020 – Belt arrives in Austria
7/7/2020 – Gentle enquiry as to progress, told need to order some material for the hinges.
10/8/2020 – Follow up again, told the workshop needed a new floor and to reinstall the welder. My belt will be “the first thing done”
18/9/2020 – “Belt was finished yesterday”, just needs the welding ground back and a new liner.
4/11/2020 – “Forgot all about it” “the parcel is still in the office”.
10/12/2020 – “Had to buy a new welding machine”
4/1/2021 – Chased via Twitter DM, no reply.
14/1/2021 – Chased via Twitter DM, no reply.
19/1/2021 – Chased via email, “have had flu”
31/3/2021 – Chased via email, no reply.
12/4/2021 – Chased via email: has been ill, will ship this week! Lots of apologies.
27/4/2021 – Chased via email, no reply
22/5/2021 – I publish this post
22/5/2021 – Twitter reply saying it will ‘ship this week’
4//6/2021 – I tweet ‘still nothing’
22/6/2021 – I get an email saying it has shipped with a tracking number
2/7/2021 – The tracking number shows the postal service is still waiting for the parcel from the sender, I chase.
10/7/2021 – I chase again, I’m told they will follow up with the post office on the 12th

20/7/2021 – Belt finally arrives!

Super Heavy Straight Jacket

I recently sold a moderately heavy SJ I bought from RubAddicition some years ago, having grown out of it, and I’d been on the hunt for a replacement ever since.

So here it is, made by RubberWerk, this is 3mm thick latex, weighing in at 10kg (over 20lbs) on its own, and add in the StudioGum helmet at another 2kg and it makes for one intense ride.

The stupidest / hottest thing I’ve ever done

This is a story, with some true bits, and some embellishment. I hope you enjoy. Please always play safe and let people know where you are and when you’re due back.

We had been corresponding online for a while and I’d finally plucked up the courage to arrange a session with him. We were in the same town, and not far from each other, but I was very inexperienced. I’d never even set foot in any kind of dungeon before and the only gear I owned was confined to some cheap white cotton rope.

He offered me a one time deal, valid for that first play date only: let yourself in, tie yourself up, don’t see him until the end.

It was a rediculous offer. I’d never met him, but the pages of hot guys tied up in the same way on his website was too much to resist. I said yes. Stupid, stupid Loki.

The day came, and I had his address. I had to let myself in at a precise time and found myself wondering the streets outside for an hour because I was early, all the time thinking both THIS IS AMAZING but also THIS IS SO STUPID. I’ve never met him, we’ve never even spoken, just messaged online, no one else knows where I am, and it’s before the days of smartphones so I can’t even be tracked. FUCK. WHAT AM I DOING?

SHITSHITSHIT. It’s time. Now or never. Decide. I find myself halfway to the door before I’ve even had time to think. Guess my dick is doing the talking now.

He’s given me the location of the front door key underneath a specific flower pot (how original), but nothing more. I find it. I glance at my watch, it clicks over to the hour exactly and I turn the key. I step inside and close the door behind me. And exhale…

I see a sheet of paper on the floor:


Take off all your clothes. Fold them neatly on the floor. Step into the playroom to your left and you’ll find further instructions.

Follow them exactly.

I take off everything. I suddenly feel incredibly vulnerable.

But I find I need a piss. I see the bathroom door is open down the hall. This is ok isn’t it? Is he here? Is he watching? OK, well, nervous wee time it is. As I proceed down the hall I pass the open door to the playroom, and I stop briefly to look in. It’s all dark, with a single spotlight illuminating a metal chair in the middle. It’s just as I’d hoped and my dick twitches.

I quickly use the toilet, and head back to the playroom, take a breath, and step in towards the chair. I see a pile of gear, and some more instructions:

Sit on the chair.

Cuff your feet to the chair legs.

Put in the earplugs, then the hood.

Cuff your hands behind you through the bars in the back of the chair.

The ankle cuffs are leather straps with a simple buckle and they go on easily. As I bend down to cinch them up, I notice I have a huge erection that pokes me in the stomach. Hi there. Still in charge I see.

I roll the foam earplugs up and stuff them in. Sounds are dulled, and I notice how quickly my heart is now racing.

I pull the leather hood on. It just has a mouth opening, but it smells like nothing I’ve tried before. Pure bondage. All the guys that have been in it before. It’s heaven. I fumble with the laces – I’ve never done this before – and it feels like an age to get it done all the way up. I tug on the ends of the laces and feel the hood envelop my head, the last traces of light disappear, and the remaining ambient noise shut off.

I click the handcuffs on one wrist, reach behind me and feel for the other end. I pause. This is it. Once I do this up, I’m stuck here, no going back. Click.

I sit there in the still darkness. All I can hear is my own heartbeat, and I can feel my dick twitch in time with it.

God this is so stupid. What have I done.

How long have I been here now? A minute feels like an hour.

Still I wait. My breathing is rapid in anticipation. I can’t hear anything. All I see is black. Come on…

Suddenly a hand is exploring my body and I gasp. The hand rubs my hooded head to calm me down, then moves to my dick. The gasp becomes a moan.

My leg straps are released, and the handcuffs undone, I’m pulled up out of the chair and pushed up against the cold steel scaffolding bars. I wince, but leather straps are quickly applied to keep me in place. My cock and balls are bound up with some kind of rope, which makes me extremely sensitive. I feel lube applied, and suddenly I’m in a different plane of horniness entirely.

The next few hours are a blur and no text can describe really describe them, except to say that at the end, the hood is pulled off and I see the sweaty, lubey, spunky mess of myself in the mirror. I am briefly disgusted by myself, then I look over and catch the face of my – until now – unseen captor, and he smiles.

DIY Breathplay Manifold

IMPORTANT: Breath control is dangerous even in experienced hands, but even more so solo. NEVER use a device such as this on your own.

I haven’t posted this bit of DIY before as I’m in two minds about giving people such potentially dangerous tools, but then it’s just some bits of pipework so it’s hardly an immense secret. That said, although it’s simple, this is for people that know what they’re doing and are looking for something to make play easier and safer.

The idea of this build is to give you an idea of what I made as a framework to customise for yourself; there’s no right or wrong setup although there are some fundamentals.

The main components are half-inch PVC pipe and fittings. I’ve used:

  • 90 degree Ts
  • Plain sockets (to provide a female connector for the poppers vial and for the gas mask hoses)
  • Ball valves

In my case everything is solvent welded together (you just wipe some gunk in the pipe, push, wait a minute, and it’s stuck forever) but you can get screw fit. The pipe can be sawn to the right length but for a couple of quid you can get cutters which make it super easy.

I’ve used grey half-inch pipe throughout but use whatever colour you like. If you’re in the UK then will supply your needs.

As far as kink components go:


Be aware that there is a quarter turn between full on and off, so precise dialling of (eg) poppers can be tricky, but it should be ok for most needs.

Gas mask connectors

If you attach a socket (i.e. female to female) this will give you a slightly larger outside diameter which will enable you to attach a standard 40mm gas mask hose. I used the type that has a clip fitting so I could remove one end and then a stainless steel jubilee clip to tighten it on.

I actually have both a male and female end for flexibility but the male end (the one on the far left in the picture above) along with an extension is probably the one you’ll use 90% of the time to connect to another gas mask.


For this, I have a piece of 20mm outside diameter clear, flexible, PVC tube with a small hole in the side push-fitted to a socket. The poppers then sit in a (delightfully-named) bijou bottle. Open the valve and air is drawn through. By juggling the main inlet valve and the poppers-section valve you can change the concentration.

I use a little bit of hockey tape (the kind for shins, not sticks – incidentally this is perfect for sealing vac beds too as it doesn’t damage rubber) to improve the fit of the clear tube into the socket if I need to.

Rebreather bag

The same setup as for the poppers (20mm clear PVC flexible tube) works to push fit in a regular anaesthetic bag.


With the same hockey tape, I’ve found a nitrous cracker fits into the inlet valve quite nicely. In hindsight I would have added a valve to the main exhaust too, so that I could close everything, fill the rebreather bag with nitrous, attach my victim and then allow it out as I wanted.

40mm to 20mm conversion

You might want to go from 40mm (gas mask) to 20mm (standard anaesthetic). You can either do this using the rebreather bag setup, or I have a converter I found somewhere once but can no longer find.

Extra caution

If you have a very long hose between the setup and gas mask, be aware of tidal volume if you are rebreathing (i.e. the lung volume matches the total volume of all the tubes and so on).

I am deliberately not covering closed-circuits as that needs CO2 absorption, valves and other stuff that’s very complex and frankly dangerous.

Visit a professional if this is your kink.

Loki’s Lube Lab

This is a rehash of some existing silicone lube recipes, but with more of a focus on EU ingredient suppliers, and, well, proper units.

The end product is basically indistinguishable from the ‘Mr B Glide’ silicone lube I’ve been using for general latex donning, shine, and fun. The net cost will be over half of retail, which will be a serious saving over time.

Ingredients (all are cosmetic grade):

Dimethicone 1000:


Phenyl Trimethicone [sorry, this is a US supplier but you don’t need much]:

Volumes needed for approx 1.5 litres:

1L Dimethicone 1000
0.6L Cyclomethicone
25mL (a shot glass) Trimethicone


Combine all of the above into a clean bucket and mix really throughly. You can use a whisk, spoon, immersion blender, or paint mixing paddle on a drill, just as long as it’s spotlessly clean.

Any ‘haze’ from incorporated air bubbles will dissipate.

You can tweak the amount of cyclomethicone up or down to make it thinner or thicker as you prefer.

You can then decant into a fliptop bottle, pump dispenser, or an old lube bottle. Done!

I’m sorry, I’ve not been keeping up the blog with new images as I post them on twitter, so here’s a big load of them all in one place ^_^

Fantastic Rubber

IMPORTANT: I can no longer recommend FR due to their owner’s apparent affiliation with a far right party.

I’d been lusting after a Fantastic Rubber catsuit for a long time. They look great, and their pattern making ability is legendary. Ideally I’d have gone to their workshops just outside of Berlin, but I wasn’t going to go anytime soon for an event so it would have been an additional cost on top of a suit that isn’t all that cheap to begin with.

Their suits are all made to measure, that’s “included” in the pricing (and the more you buy per year the greater the discount) so you have to fill out a complicated form (in German) and send photos of yourself if you’re doing self-measuring – although it’ll need another person. A somewhat nerve wracking process and it’s an expensive mistake – measure several times and watch their videos to get it right!

The end result is probably the most perfectly fitting suit I own now – STR off the shelf sizes are pretty close and more accessible in pricing, but for the Boob Suit there was only the one option.

FR were really good at helping choose the silicone boob sizes (I mean, you can go to insane sizes but I wanted something more in keeping) and the order update process was fantastic. You got a constant tick down of the numbers in front, and the stage your suit was in manufacturing. All told it was about a 3 month wait.

Getting the suit on is “interesting”. I’ve owned neck entry suits before (and FR only do neck entry) but I went for a 0.2mm thin gauge of latex, and as it’s expensive the donning and removal process is stressful: no sharp nails, no rings, no piercings. There’s also a special pocket for the boobs, and a halter that you pull over your neck once you’re in, so instructions are needed!

It isn’t a spur of the moment play item, nor is it for heavy play, but it looks amazing.

The Transformation Machine

To celebrate the coming together of my Rubber Doll outfit, here’s a short video of my transformation.

The Studio

It is almost a year to the day, as I write this, that we moved into a new home. With that came the opportunity to build a bigger playroom and go for a lighter, airier space rather than the previous industrial grunge (not that there was anything wrong with that).

Having learnt a bit more about our styles of play, and how the impacts to my health had changed things, prodded us into creating a space with five recessed overhead hard points for flexibility in rope bondage, as well as a focus on two pieces of furniture: a bondage chair and a retractable table.

I’m really happy with the results.
