Mini sanding block 2.5x4cm

cults3d

I often make small objects in 3D printing, and sometimes I need to sand a few parts evenly, without necessarily wanting a more aggressive acetone polish. I made this little sanding/polishing block, which accepts 400 to 5000 grit sandpaper. A 2.5cm by 8cm strip of sandpaper is ideal . The notches allow you to tighten the sandpaper on the wedge so that it doesn't move when sanding, but you have to force it a little so that it closes, and to separate the parts with the used sandpaper, a fine blade or a screwdriver works very well in the center of the 2 blocks.
