Miniature reproduction of the famous impossible table
Very easy and fast printing. Join the triangular parts, each with its own arm, with a drop of glue
Join the two parts with fishing line, string or anything else you deem suitable.
I recommend tying the external parts first to allow you to find a length suitable for the draft and finally tying the internal arms while maintaining the draft of the shelves. The holes on the triangles are 1.5 mm, so if you use a fishing line, take this measurement into account to also allow the knot
