Even though no one asked for it, here is yet another impossible dovetail box. But this one has a twist! Rather than sliding the two halves apart to open, this box is opened by turning the lid an eighth of a turn.
I have also included a version that can be printed with integrated magnets to keep the lid from twisting off on its own. You will need to pause the print to place the magnets inside the part. The magnet spaces are sized for 6x3mm disc magnets. The amazon link for the magnets I used is below.
If you end up printing this, I would love to see photos of the print!
UPDATE 1/2 4/6/2019: If you decide to print the version of the box with magnets, the height that you should have the print pause at for the top half magnets is 32mm, and the pause height for the bottom half magnets is 17mm.
UPDATE 2/2 4/6/2019: I've edited the box lid to have a thinner top to allow for more storage space.
