These four sizes of Anti Oloids are a graceful shape which rolls drunkenly with a gentle push. They’re sized from approximately 100mm, 60mm, 45mm and 30mm long with a thickness of 3mm, . You can easily scale them up — the thickness will increase proportially but they’ll work fine. Making them smaller may increase printing difficulty as they get quite thin.

I printed them on a Bambu X1 with a wide brim and auto tree supports.

Printed in ABS, but they should also print easily in PLA or PETG.
