Small Magnetic Sanding Block

thingiverse

This is a small sanding block that uses magnets to secure the paper in place. I find it comfortable to hold and a great size for most detail work. I printed several of these and loaded each with different grit sandpaper. It works OK without magnets too using friction to hold together but it is better with them. Magnets: 4 - 10mm x 3mm or 10mm x 4mm neodymium magnets (There is also an stl file included with no holes for magnets so you can add your own) Sand paper: ~115mm x 30mm strips Cutting a standard 230mm x 90mm (9" x 2 2/3") sheet into 6 pieces will result in the correct size (see images) Assembly: Remove supports. I use a very small amount of hot glue to help secure the magnets. Super glue doesn't seem to work as well. Be sure to align the magnets correctly before gluing.
