A 15x15x27mm version of Macaque's magic latern for knitting projects or other stuff. The inner diameter of the ring is 3mm. The are no-ring version in case you'd like to change it or to not have it printed at all.

Created for SLA printing, but it works with FDM too. Thought, it's quite small for it, so you’d better turn "Print thin walls" on if you slice it by Cura
