This is a micro sanding tool specially made for detail work.
It's a shameless copy of an online favorite.
The model was made using tinkercad and printed at 0.2mm layer with 15% infill.
I will take the model down if the original designer of the piece complains about it as this is not in any way an attempt to steal his work.
I made two versions of it. A regular one and a curved bow.

cut a 5mm sanding strip and glue it to the sanding tool
