We're VERY excited to be joining you lovely lot at #MRW16 tomorrow! We've been working hard to make sure we've got plenty to show you, including our new Breathplay System. We'll only have a few in both the 2 and 3 attachment variants so make sure you come find us early if you want one!

We'll be debuting our redesigns for several products at #MRW16 on Saturday. Make sure to come and check them out in person and see the improvements for yourself.

They'll be available on our website afterwards and the STLs will eventually be uploaded to patreon.

Come find us at #MRW16 on Saturday for Breakaways for only £5!

The perfect tool for safer and more convenient breathplay. No longer worry about screwing/unscrewing components in a panic, just pull the breakaway apart! Or use it to quickly change between your attachments.

We have officially met our printing targets and we should be well stocked for #MRW16 on Saturday.

Now to figure out how to fit it all in the car...

Spaghetti for dinner, anyone?

Decided to see what timelapses had been saved on the sd card in the printer - found this beauty!

This is what happens when you don't triple check for floating geometry in your designs 🤦

Less than 200 objects left to print before #MRW16!
I think we're on track...

Enjoy a cheeky timelapse of the new S10 table design

I've redesigned it such that it prints in two pieces, neither requiring many supports. The only thing that made the old version so rough is the requirement for supports.

The new file will be uploaded to patreon in due course :)

Product Design: S10 Table

On the left is the new version, on the right is the previous version. The difference in surface quality is pretty clear to see :')

I think that's another design done? What do you all think?

Product Design: S10 Table
So I have a plan and a design for the table being printed with zero supports... but does anyone else see the similarities here, or is it just me?

Product Design: S10 Table

The problem: It requires a lot of supports on the underside giving it a really rough looking surface. Yes, we could print it "stood up" but that would compromise it's strength.

The task at hand: come up with a new design that doesn't require so many supports.

Just a satisfying timelapse of the Side Valve being printed. Enjoy x

Product design: S10 Standard

Issue: In the new orientation supports were required for the surface that the valve presses against, making the surface rough causing leaks.
Solution: Tweaked it such that supports weren't required. Works a treat!

I think that's another design finished!

Product design: S10 Standard

Good news and bad news.
Good news: we got the individual bits to fit together
Bad news: despite working on the side valve, this same geometry is leaky in the standard.
The difference? We've had to rotate the whole thing 180degrees...
Time to troubleshoot.

Product design: The S10 Standard
Now that we have an invertible valve, can we fit it into the S10 standard to allow users can change airflow direction?

The problem: how does it fit? Ideally, we want to keep an internal NATO40 screw thread too for blockers/restrictors.

Product Design: S10 Side Valve

While we knew this would also be compatible with the FMJ08 (or S10.2 as some people market them as) and FM12, it looks like this also fits really nicely in the MF-11!

I think I've talked about this side valve enough now. Time for the next project!

Product design: S10 Side Valve

After more rigorous testing, we weren't too pleased with the amount of airflow. A quick redesign and a print later and we have what I think is the finalised S10 Side Valve...

I was pleased with the previous version. This one looks even better 😍

Two more items printed, only about 500 to go before we're ready for #MRW16.

Part of me wishes I hadn't made this spreadsheet. I think I was better not knowing how far off we are :')

Product Design: S10 Side Valve

I think it's done. It seals in both orientations. The wider rim covers the messy part of the mask, the screw is smoother. Most importantly, it doesn't honk! More rigorous testing required still, but I'm happy so far.

What do you think?

James
May 29, 2025 at 3:30 PM
Very interesting! I'll keep that in mind in future. In the meantime, I have just widened four points so that the corners aren't quite so "sharp". Initial tests seem to suggest this has fixed the issue :)
May 29, 2025 at 3:26 PM
Product design: Fixing the new side valve. We cracked it!

The “crosshair” needs to be reinforced. When clearing the supports from the valve, I may have cracked it, causing the goose honk.

Easy fix (I hope). Back into blender to make the surrounding a little thicker.

Results of the S10 Side Valve redesign:

Looks great… just a slight problem...
Your mask will sound more iconic than Darth Vader’s. (video requires audio - quite loud, you have been warned).

Product Design Post!
I'm working on some improvements to the S10 side valve:
Smoother screw,
Angled base for better seal,
Internal chamber for valve inversion,
Wider rim for security/concealment,
Supports a more robust valve to prevent accidental damage.

Let me know your thoughts!

Expect an uptick in posts from us as we're excitedly preparing for #MRW16 in June (hosted by @manchesterrubber.bsky.social)!

Show of hands: who else is excited?

(Posts are going to be made by James for a bit as he has a bunch of free time and he wants something to do)
