The file 'Impossible Dovetail Puzzle Box 3D Printer Model' is (stl) file type, size is 42.5KB.
As seen on Chinese wholesalers, this is a replica of the impossible dovetail puzzle box. It is ingeniously simple in design, but it can boggle an experienced puzzler's mind for a stretch.
Fair warning: there are sharp points and edges, and the tolerances for the ball bearing might require you to hone out the holes a bit.
If you remake this, for attribution please simply note that it was inspired by the wooden puzzle boxes found around online.
Note: TWO magnets are REQUIRED for this to work properly! Also one ferrous 3/8" (9mm) steel ball bearing. If you use a 10mm version, enlarge both holes appropriately.
