Impossible Dovetail Joint Cube (IDJC) inspired by "Clickspring"

Two days ago i watched a video of the "Impossible Dovetail" on the "Clickspring" channel on YT. For ambitious woodworkers this is a very common project, but Chris machined the parts out of aluminium (aluminum for U.S.) and brass. I really liked the look of this "toy", but i don't have the skills nor the machinery to make one myself. But hey, i have a 3D printer and some minor CAD knowledge. So here is my interpretation of the Impossible Dovetail Joint Cube. The main difference to Chris's IDJC is the locking mechanism. His version uses a locking pin, mine is held together with magnets. Enjoy ;-)

Print Settings

Supports: No

Resolution: .2mm

Infill: 20%

Notes:

I have included 2 versions. A standard dovetail and one with fillets. Just choose the one you like. A matched stand is also available.

Printable without raft & support. All files already "NetFabbed" and in right orientation for printing. I added about .2mm tolerance, any normally calibrated printer should have no problem to print this properly. You will need 2 Magnets (3mm diameter, 2mm deep) to hold the Parts together.

The red Cube is a 75% version. So scaling works, but (of course) the magnet holes won't fit anymore and the tolerances are more tight.

Post-Printing

Just glue the magnets in place and you are done!
