Double Dovetail Puzzle Stash Box

Update: Figured out how to export the files in the proper size and orientation from Inventor. Changed the fillet to a chamfer at the bed side of the box for a better print. A double dovetail optical illusion box with a magnetic internal pin system to keep people puzzled about how it was created. There's also a secret compartment inside for hiding small things. In order to release the pin inside, give the bottom of the box a good smack on a hard surface until the bottom pin falls off of the magnet in the upper box into the recess below. you need some 8mm magnets that I found at dollar tree (most craft stores have them) to glue into the top box recess, and then glue the top pin over top of the magnet so that the bottom pin doesn't magnetize too strongly to fall down. you'll also need a M4x16mm screw to thread into the bottom pin part to create a magnetizable pin (the head of the screw should be about 7.7mm).
