power file or belt sander for angle grinder

This belt sander was made for a Bosch 14-125 CIE angle grinder with speed control. I do not recommend using it at full speed! It might also fit many other belt sanders but make sure you use one that allows for a low speed setting.
It works really great!

You require 2 bearings (22x7x8), a spring (about 15-16mm diameter x 60-70mm; i do not remember exactly) and a thin sheet of metal except for the printed parts. Also a little bit of glue and filler.
It was made for 13x457mm sanding belts.
