Edit: - Added 25mm wide version 

         - Added 46mm wide version (be careful, it is a bit tricky to move with the tightener because of very wide body.)

Please, make sure you check my new version for 330mm sanding belt :)

And open version here:

I like all these sanding block sets that we can find on the internet, but I wanted some round ones and some other shapes.

I also wanted a tool that would make it easy to stretch the paper.

It's very easy to assemble. All you need is just M3x10mm hexagon socket screw or you can use my nut and insert M3x20mm hexagon screw.

Be careful - the screw is mounted right to the plastic so be careful when tightening.

Everything is designed to print with standard 0.2mm profile of PLA or PETG and without support.

If you want some specific shapes of sanding blocks, please leave me a note or comment and I will make it for you.
