Interlocking puzzle

thingiverse

I designed this puzzle as a tribute to [this product](https://www.seriouspuzzles.com/dirty-dozen-metal-interlocking-puzzle-by-puzzle-master/?utm_source=share&utm_medium=ios_app&utm_name=iossmf) which sold out due to a Reddit user's enthusiastic recommendation. The original metal version is an excellent purchase, so grab one if you can get your hands on it. To build this puzzle, print 12 copies of the model and figure out how to assemble them - I haven't got that far yet. You'll find my FreeCAD source file included below. The model's parametric design allows you to adjust settings for total size, tolerances, and fillet radii. If you notice a loose fit between parts, consider tightening up the tolerances. You won't need to edit the sketch itself; just tweak the "param" spreadsheet instead.
