Hello the MK3 Dust shoe supplies files to download to 3d print. The file provided is a .step file. I use Cura and it can’t open it. Can an STL file be provided to that download? the magnetic dust shoe for the Mark2 had an OnShape file for it. that i could work with.

@carmine80 These should work. If not, let me know.

Awsome. thank you. i modified them a bit to allow for more air flow on the underside with tinkercad. but that worked great

@carmine80 I’m happy to help. I don’t like Z dependant shoes, but I figured that I would try this one. I have not changed my opinion. 😀

i know what you mean. the magnetic shoe for the mk2 worked well for me. but i don’t think it works on the mk3.
