Give to anyone and let them wonder how these impossible dovetail joints were assembled...
Like all my impossible objects, I've published a tutorial on my blog to model this with inventor using the master sketch method (http://wp.me/p3gI7M-64)
No real difficulty to print these pieces. Mine are in PLA, 0.25mm layers, 2 shells no support. The overhangs shouldn't be complex to print.
There is a 0.5mm clearance in the dovetails. I first printed these piece and they were sliding too easily to my taste. You don't want the puzzle to come loose when someone is handeling it, it would ruin the charm.
So I've regenerated the files with a 0.25mm clearance (in the zip). I just reprinted the PartA in 0.25mm and with the partB 0.5mm the result is perfectly snapped.
