Grandios zu sehen, wie präzise dieser Lasercutter aus einem drei Millimeter dünnem Stück Birkenholz eine Spiralschale schneidet. Wer so einen Cutter haben sollte, kann sich hier die Mustervorlage holen.
This is a set for two different bowls- just delete the frame you don’t need. They’re designed for 3mm birch plywood, and should be already scaled properly. In case you still need to scale them, the file also includes a 400mm scale vector; that should help keep things simple:)
