- Print the M4 version for your Alfawise U10.
This is a new leveling wheel/knob I drew up. I first printed the large CR-10 wheel for my Alfawise U10. Then I found it was too big. I took a few measurements and after a while I was drawing it using Onshape.com. The chamfers make it look like a luxury car rim -- it turned out great. The prints in the photos used 0.6mm nozzle. It can look better with 0.4mm.
PS: I made the M3 version first, but I'm a dunce and did not realize my bolt was an M4. I made a variant for M4. I posted both thinking it may have other applications.
