Easy and cheap way to transform an ORAL-B toothbrush into a hand detail sander for finishing 3D prints.
- Cut off the bristles of an old toothbrush.
- Print some of these pads and glue a piece of sand paper on it.
- Press the pad into the toothbrush.
I print several pads and glue different grain sand paper on them.
The base sketchup file is included along with some variations and experiments.
