Can’t wait to get home to use this 12” giant bull master I 3D printed from files by @kdxgp.bsky.social. I did modify length to 12” since I’m long and need the headroom. MeatUp East in FLL prep 😜 @tonyvegaxxx.bsky.social #bullmaster357 #penispumping #ballpumping

Small updated on my pump configurator: You can now get some more stats about your config by activating the "Info Panel". Also added Spanish and Italian translations (with help of AI, any feedback if it's actually correct is highly welcome)

After what was a hell lot more work then anticipated, I just released a complete overhauled version of my custom pump configurator at pmpcfg.kdxgp.com . Go check it out and I would love to hear you feedback! If you spot any issues I would appreciate if you let me know, so that I can fix them.

Many years ago i needed a quick solution for separating water from my pump. What started as 5 Minutes workaround envolved to a valuable companion for years….

Oh yeah! Scaled up build to 180mm diameter (~7.08in), with 70mm opening (2.75in), of my two stage split design is a success! But I have to admit I found a minor issue with the gasket thickness. I'm talking about 0.1mm... maybe I'm stepping into over-engineering territory...

🚨 BETA TESTER WANTED 🚨 I've built one beta test version of my 2-stage split entry design and it's hungry for some action (check pics for specs). Head over to x.com/KDxGP/status... to maybe be the lucky pump lab rat 🐀😉 (sorry for the none-X/Twitter-users, I just have to most followers there)

2nd test-drive of my 2-stage split entry design prototype. Still holding with no leaks. It has a 70mm (~2.75") opening, which is good for about 1h before I get stuck. But luckily I can sparated it 😁 #cockpumping #cockpump #ballpumper #ballpumping #penispumping #penispump #pumping #vacuumpumping

Heureka! The FINAL (at least I hope so...🤞) prototype of my 2-stage design with a split opening. 👉On to test-driving it!

I started work on publishing my PMPCTRL automatic pump setup. Still a lot of writing, making images and cleaning up software repositories to do before I can call it 'published'. You can track progress on www.kdxgp.com/pmpctrl Feedback and input are always appreciated. #cockpumping #ballpumping

I'm inching closer to a viable solution for my 2-stage split design. But: 1) It needs four screws+shims. Putting it on/off is fiddly. 2) The gaskets wear off and need replacement. They're easy and cheap to make, but ideally you would require tools (hole-punch) to make. Your thoughts on that?

As Edison has discovered lots of ways how to not make a light bulb, I'm finding new ways of how to not make a 2-stage split pump. But I'm only at 6 attempts so far.

If you want to spot @extremgirthpump.bsky.social pumping in the woods, you'll need to look more carefully. Otherwise it will be hard to see him with his new custom camouflage pump (kdxgp.github.io?c=%2373835e&...). #cockpumping #cockpump #penispumping #penispump #hugebulge #monstermeat

After years, I finally treated myself to a new ball pump! Custom sizing, color, and designs available from @kdxgp.bsky.social! I may have misjudged the size XD, but at least it is significantly lighter and I can't wait to get into it 😈

If I pump my pump 🤔 ... will it get bigger? Latest custom-built "big blue" (4" x 7.87" x 12.3", kdxgp.github.io?c=%2332599c&...) next to 3.15" x 5.91" x 9.78"
