MiniGrinder

thingiverse

I got a notice that the files are not downloadable so I will add a second try to upload it PLEASE SEE THE SECOND UPLOAD I had to work on several small things and needed a small grinder for plane grinding with sandpaper, so this small tool isn't as stable as metal construction but does what it should. I use nails (about 3 cm diameter) as an axis for the both rolls and even smaller nails in the holes at the side to tension the sandpaper if necessary; don't forget to glue at least one of the rolls and the nails to have a tight, stable connection. Take a small stripe of sandpaper (3 cm x 25 cm) and fix it (best with superglue), connect a multi-tool gadget to it to rotate the sandpaper... and work. Have a lot of fun with it.
