Small Printable Sanding Block

A small basic sanding block, square like the one my dad had when I was a kid. Very handy for cleaning up small models, and quite sturdy in PETG.

Unlike some of the other sanding blocks I've seen, this block requires no external parts/screws/etc - it's all printable.

Sized to fit cut strips of 3.6" (x 9") sandpaper.

The screws were adapted from:
