Double Dovetail Puzzle Stash Box

Update: Figured out how to export files in proper size and orientation from Inventor, changed fillet to chamfer at box bed for better print. A double dovetail optical illusion box with magnetic internal pin system keeps people puzzled about creation method. A secret compartment inside allows hiding small items. To release the pin inside, give the bottom of the box a hard smack on a hard surface until the bottom pin falls off the magnet in the upper box into the recess below. You'll need 8mm magnets found at dollar tree or most craft stores to glue into top box recess. Glue the top pin over top of the magnet so the bottom pin doesn't magnetize too strongly and fall down. You'll also need a M4x16mm screw to thread into the bottom pin part, creating a magnetizable pin with head about 7.7mm.
