It's funny how many people have redesigned Gridfinity. This looks like a solid improvement in a few areas. If you make it, let us know how it goes.
The 4040 adapters ought to have magnets, though, IMO.
I use a Prusa MK3 (not MK3S/+) that I got in 2018. Later this year I hope to get an MK4 to join it, and maybe a Voron 2.4 for big prints. My first printer was a SeeMeCNC Rostock MAX from 2013. Its controller board died for the second time just before I got the MK3, and I never fixed it.

Once I built a pumpkin chucker. Another time, I built an LED cube.
Interests: 3D printing and making in general, synths (playing and making them), learning the bass guitar (rock, jazz, funk), FPGAs and electronics, pinball. I spent 40+ years obsessively coding and studying computing, but that interest has finally cooled.
