Magnet Snap-together cube with hexagonal X-section

A 4cm cube, cut into two identical halves, but along a diagonal, producing a regular hexagonal cross-section. Snaps together through the use of three embedded magnets in each half. Uses six 6mm diameter 2mm thick round magnets. Important: I think the 3mf file will include the pause at layer 16, but if not, or if you load this from STL files, you can add a manual pause (gif shows how I did this in Bambu Studio for my X1 Mini). At layer 16, the print pauses, and you can slot the magnets into the spaces. Remember to orient them North-North-North in one of the pieces and South-South-South in the other, so they snap together instead of repelling! The cube is hollow (the smaller cube-shape inside will fit a pound coin - see photos), but note that, thanks to the unique hexagonal cross-section cut, you wouldn't be able to fit a solid cube snugly inside (the corners would be stuck!) Prints in under 90 mins, uses 28g of filament. I've only tried it in PLA, but don't see why it wouldn
