Rounded Sanding Stick

I like the idea of the Sanding stick by multiple artists here on thingiverse, but I noticed that none of really worked for sanding circular or rounded shapes. So I've created this thing, which you can use to sand the convex of any rounded object with a maximum radius of 55 millimeters.

I have also included the SolidWorks files for those who want to further customize the curve of the part.

You will need M2x16 screws and nuts for this assembly which can be found on Amazon or a local hardware store.
