125 mm sanding block

I have a lot of 125 mm sanding discs, but sometimes I do not need a power sander and I'd rather sand manually. To reuse the discs I made this sanding block, which also features an attachment for the vacuum cleaner on its handle.

Three available handles sizes: Large, Medium and Small to adapt to various hands sizes. The one shown in the picture is the large version.

You need to glue a circular grip on the bottom part so that you can attach the sanding discs. You can also find precut self-adhesive grips on sale online.

I provide the STEP files but if you use OnShape you can clone the original project (public) [here](https://cad.onshape.com/documents/1da6361ba6e62a6a14d839a6/w/a50eadcdfa13a2031ed4675b/e/3e5d9fc4d4ddf060efc0a505).
