3D Heart jigsaw puzzle

(Updated print profile to fix issue with bottom of box not being flat, 6th Feb 2025)

Why don't you surprise your puzzle-loving partner with this 16 piece 3D jigsaw puzzle of a heart?

The model comes with a box to keep the pieces (or the assembled heart) in, and the box has a hole in the lid so it can double as a stand to display the puzzle once completed.

I printed this in Bambu PLA Basic.  It came out OK but for pieces where the interlocking parts were printed with supports you may need to work them back and fore a few times before the move freely.  For my previous puzzle I used a 0.2mm gap between pieces and that turned out a bit loose, so this time I went for a 0.15mm gap; maybe 0.17mm or so would be ideal..

Have fun solving this; it only has 16 pieces - how hard can it be!
