This is the first version of the KB3D Air-System. Designed so you can connect multiple attachments to a single gasmask. With the integrated valves, you can turn on or off each of the connections.
Comes in a 3 valve or a 2 valve design.
The device itself, has a connection at either end, which is not controlled by a valve (depending on your use case, you may want to block of the ends). Then in between those two connections you have 2 or 3 valve controlled ports.

Today I am releasing updated modules which are compatible with all the gas masks listed above. The changes to these modules are substantial enough to be considered a new version.
All still compatible with the V2 insert.
Fleshlight - The curved version of this flashlight has been a WIP for a while. Although the curve improved the chin fucking problem. The module has print problems. These have now been fixed. In addition, the front has been redesigned to grip onto the fleshlight bet...

Hey all,
I think due to my poor memory and the way Patreon works, some folks are unsure about who GP5 module works on what. So I am re-uploading the files so hopefully it's clearer.
The system I am uploading is the Original GP5 platform, which I am now dubbing GP5 Modular System,
This requires removing the valve system on the front following this guide 2025-05-27 19:05:41 +0000 UTC

Hey all,
I thought I would make this post to update you on the S10. The S10 has been my most popular gas mask by far, but the original posts were done so long ago I thought it's time to post below all the currently used files.
Over the past few weeks I have been working on the flashlight, I think I have a newer version which works well. Over the next few weeks I aim to update many of the modules.

Hey all,
This is a major overhaul and design refresh of all the adapters, blockers, T connectors and breakaway, whilst including new Y connector, and one way valve.
This system utilises the same core mechanism, which improves simplicity and increases customisation options. Utilising there RB rotatable connectors.

Hi All,
I have just released the first commercial Tier. Take this as a trial run. This is the chastity items.
From my previous post I have changed the terms slightly. Instead of up to 10 orders for the first tier, it's now any number of orders up to a total value of £500.
There terms are subject to change as I am still getting feedback, and will still love more feedback, if you are interested.
This tier is currently set at £20. If this changes, it will not c...

Brand new item. This small gas mask filter like device contains two chambers.
Twisting the box, which change between chambers A and B.
There are three different end plates.
To assemble, take the Aroma box base, so that the small 3 cylinders are pointing up (I.e the base should be flat against the table). take the aroma box body and gently place it on top and align the holes. the holes should be back to back with the base. if you align the holes, the one of the set o...

Here is RubberBunkers version of a smell box, It's designed on a typical filter. It uses RubberBunkers rotatable valve system.
I have tested it to function with my Bambu lab X1C.
I have re-uploaded the female/male connectors and inserts although the are the same for all the rubber bunker items.

Hey all,
Over the last few days, while procrastinating from my actual day job, I have been thinking about the Commercial Use. I have put together a draft 1 of the agreement.
I would love to get your feedback. I think (might be wrong) but most of the agreement is sort of assumed. But please if you have concerns with any aspect of it, please let me know either via message or comments below.
The main thing I am thinking about is the cost. Is the cost fair? I fully accep...

Hey all,
So at the moment there are a few things I do not sell. 1) I don't sell my chastity cages. 2) I don't sell any of my items to the European Union (Due to EU law).
I was asked by a member about a commercial license for chastity. As I currently do not sell my cages. It would give members A) the opportunity to make a little money, B) give people who do not have access to 3D printers to get the cages.
But I could also offer a commercial licence for items be...

So the first item which has been modified has been the NATO40 switch. Although I released this not that long ago, the new rotatable NATO40 connectors had to be added.
So to assemble,
effectively the Male/female inserts are first placed into the NATO40 male/female. You should have a bit of the tube sticking out of the bottom. This is then pushed into the switch body.
These items are designed to be push fit, if you need, you can adjust the size of the inserts. The inse...

Good morning all :)
I have just attached version 2 of the sodabubbler. The changes mainly include having a NATO40 connector on the import.
This allows you to attach additional items to the bubbler, for example a smell box, poppers attachment or just daisy chain extra bubblers.
I have also included the mk1 as well as the FF adapter. The FF adapter is the most common adapter needed for the input of the bubbler, as the Bubbler mk2 is also a male to male adapter.

Hey all,
I have designed a new NATO40 switch. I had designed one a while back (I'll be honest, I cannot remember if I uploaded it), but the issue was it did not let enough air through.
This new design is based on the old one, but with massively increased airflow.
The way it works is, once fully assembled the side opposite the twist handle is always open (I imagine connected to the gas mask), then twisting the handle will change between the left side and the right.

I have attached the Narrow, Standard and wide version of the Kilo cage. This is mk1 of this cage. I have not been able to test it yet, but I aim to print this over the next week or so. if you test it let me know
haven't finished printing these, so there maybe some changes, but I expect this to be the mk1.
Width - 38mm and 41mm
Length ~70mm

This is in the cell style. I have not printed it yet, I aim to print it this week. Should be compatible with the V5 rings. I aim to make multiple lengths in the future.

Hey all, below I have attached the latest version of the Shoe. I should have done this significantly sooner.
The newer version is much larger than the older version. filling the shoe better. The airflow design of this actually comes majority from the bottom of the shoe. Not from the voronoi vents on the side. This is because most of the smell comes from the bottom.
I hope you horny devils get as much use out of this item as I do.
