See “all parts” stl file for printing orientation.
I want to make some rings but if they are thin, they are difficult to hold. Moreover if you want to make a nice uniform surface the easiest thing is to mount it on a drill and use files, sandpaper to smoothen the outside. So you insert a…
measure the id of the ring, and use the size up from that. The flex in the fingers will hold it in the center. an M5 bolt goes through the center and gets held in the drill chuck.
This design uses a standard NEMA17 stepper motor as a 4th axis for a standard CNC 2418/3018. A custom deisgned mandrel serves to hold a ring in place while a standard 30 degree V-engraving bit is used to engrave soft metals such as brass.…

This is a mandrel to hold filament spools with holes from 30mm through 60mm. You'll need a 1/4" nut and bolt (about 4" long). I designed it so the end mandrel can be removed without fully unscrewing the nut so it can still be used if you…
