Cut from 1/4" walnut plywood. Rims and dots painted black.
I did have to sand down a few edges to make them stand up straight as the cuts were at a bit of a curve, and because I had the lines not fully connect. Probably wouldn’t do that if I did it again.
Stacked it would be easier to do so,
I did at first (to get off the tabs from where I broke them apart), but it wasn’t quite accurate enough to get them standing straight, so I ended up checking them 1 by 1. It was only one in 3 that needed adjustments.
