Miniature Electric Sander

This sander works well for sanding plastic it doesn't make it too hot like a Dremel. it sands at the right speed to have great control. I haven't tested with other grits of sandpaper yet. I have also sanded wood filler with it. It worked so well for me I am posting it now, but I plan to add more as I use it more.
The Electric Toothbrush is from Family Dollar $4. but many may work it has a 13mm round head I did not use the square brush yet. you would even be able to submerge the head under water for wet sanding.

Items you need:

PLA Filament
2mm x 8mm bolts (Or other if you
drill the holes for them.)
Epoxy (I used 5 minute by JB Weld)
Adhesive (3M Super 77)
Sandpaper

Printing: PLA with 6 wall thickness, 20% infill. this made it very strong for me

I used 2mm by 8mm socket head cap screws for placement and support of the Main adaptor. then snip the heads off then epoxy the adaptor in place.
