I printed the Labyrinth Gift Box (look into listed Source) but I rcognized that it move s quite a lot in the "locked" position.
So I modelled a sleeve for the box, it looks better now to use it as a gift.
IMPORTANT: sleeve is modelled to fit tight with the original model. This means that every inaccuracy is not tolerated. For me it worked well to print the sleeve at 101%, whoch should work generally.
