About this model

Cutting (perfect) circles out of paper or cardboard is not easy if you use scissors. With this rather simple construction it is a piece of cake. I used 5.2 mm pertinax (phenolic paper) I got from a donor. It's very hard, still good to work with a cnc if you have a single flute end mill. Parameters are: small depth per cut and fast cutting speed. Don't forget to engage a dust collection as the fine dust is not exactly healthy. The stl is for viewing purpose only. Do not print on a fdm-printer! Visit for more interesting designs.
