New to Tinkercad.
I imported an STL file from Cura and wanted to re-arrange it by cutting of the Nema 17 bracket at the back. When I printed this it just snapped off in my fingers. I wanted cut this out on my CNC Router in 18mm ply and add a steel bracket instead. But I don't know how to detach the bracket from the model.
I also wanted to save the file in SVG format so I can open it in Makercam to get gCodes for my CNC Router as you don't have this facility here.
Could someone tell me how to do this please.
Thanks a lot.
