1/2" Drill Sander

This is a sanding bit that I made. It is designed to fit inside of a 1/2" hole to slightly widen it, specifically to prepare a hole for a press fit for a 1/2" PVC pipe.
to use, simply print, cut out a piece of sandpaper, wrap it around the bit and tuck the ends inside the slot.

Infill should be something strong, probably more than 25%. feel free to experiment.
