I used a bunch of sanding discs that came with my rotary tool and considered buying more. The prices were high for such a simple product, and the typical size was smaller than I wanted. I measured the spindle diameter, 2mm, and added a 30mm circle as my outside diameter, then arranged as many as possible onto a sheet.
80-grit sandpaper cut into circles
The first sheet I cut was 80-grit paper, whereas I was used to 240-grit, so I am excited to use these for shaping instead of only finishing. I turned up the laser power for the second cut because not all center circles fell out, and I had to force them out with an M2 bolt. I did not use expensive abrasive paper, so the material cost was a few cents, and I ended up with two large stacks of custom sanding discs.
