30-Piece 3D Puzzle

A very difficult 30-piece 3D puzzle. Requires fairly good dexterity. It took me about an hour to assemble the first time. Requires some guess-and-check, even up to the very end.

The rhombic.stl file contains all 30 pieces arranged in their solved positions. To print, you'll need to “split to objects” and arrange each piece face down, being careful to orient the correct side down. I've already done this in rhombic split.stl. Both files contain all 30 pieces.

You may need to experiment to get the pieces to fit together well.  Depending on your particular printer and filament, you may need to use XY Size Compensation (in the Expert settings on PrusaSlicer) to achieve a good fit between the pieces. Increasing the elephant foot compensation won't hurt either, in order to make sure there's no additional interference caused by elephant foot.

Begin by printing just two of the pieces. They should fit together without needing to apply much force. If they fit too tightly, decrease the XY Size Compensation. If they are too loose, increase the XY Size Compensation.
