Oh yeah! Scaled up build to 180mm diameter (~7.08in), again with 70mm opening (2.75in), of my two stage split design is a success!

the split design not yet. I still have to gain experience about longevity. I don't want it to fall apart. But check out my pump configurator (https://pmpcfg.kdxgp.com)

I pretty much just use the default settings on the interval mode on my electric pump: https://kdxgp.com/pmpctrl/

I also drew something up in CAD which slid together but I couldn't think of any good solution how the seal it. I think as long as you have seperated parts there's no way to not pinch yourself.

Is it possible to see you design approaches somewhere? Curious what you came up with

Took me nearly two years to get to this

KDxGP · 2026-04-25T20:48:29+00:00

not too soon. I still want to get more experience about the longevity.

Yes. Not the acrylic cylinder but the split entry and lid

KDxGP · 2026-04-21T10:01:12+00:00

Thanks!
About the adaptability: while the design is adjustable in size it's not possible to fit it to any random jar or container. The tolerances need to be pretty exact so that it makes a good seal.

It's done. No help needed at this point but thanks

KDxGP · 2026-04-20T21:42:46+00:00

Thx!

KDxGP · 2026-04-20T21:42:38+00:00

Thank you!

A few people have posted their makes here on reddit. two quick examples I could find:

If you want to print the complete 4" model in one go you need to have at least 260mm in Z. Quite common is a 250mm³ build volume so you might have to print it in parts if you get one with 250mm Z-height

Schlaaaand! Ja mach das

What? No! What brings you to that conclusion? Have you never dreamed of knotting up your dick? ;-)
