4 star Dragon Ball bit holder for 1/8" shank cnc bits or rotary tool inserts. I also needed a few of these and I didn't want to make this out of wood either. I'm also including a UFO style holder based of the same geometry. The UFO one has a small recess in the middle for holding small parts.
Printing tips
Use the filament of your choice. PLA is probably the best unless you're going to leave it in the sun. The stars are tiny, so you may have difficulty printing them in PETG. 3 perimeters and 25% infill should work on most machines. No supports are necessary.
Note: The stars should just pop in and they will be snug, but if you really want to lock them in, use a small bead of glue.
The author marked this model as their own original creation.
