Sanding block

thingiverse

I do a lot of post-production sanding, so I needed a sanding block that would be easy to swap out paper and hold it firmly in place. To prep prints for fill and paint, I buy 1-1/2" emery cloth in bulk rolls and it works great. All you need is to print the two pieces, two M3x10 screws, washers, and nuts. Then a piece of adhesive craft foam - I bought mine at Michael's. The nuts fit snugly into recesses in the bottom of the sandpaper block.
