Sanding Block 25mm - with 3d printed screw

The sanding block is a really cool tool - but i didn't have the right screws. So i borrowed some from the "nut job" design :)

Please note that the screw is a loose fit by purpose -> this is because how some slicers are handling outer diameters and because some printers' extrusion tends to be problematic with small gaps. If you feel uncomfortable with this loose fit, enlarge the screw by 1-2% in x/y direction.
