Labyrinth Puzzle Gift Box - Bottom part with tighter tolerance for better locking

I Love the Original Model, however, the two halves did not hold together well straight out of the Printer, so this remix features the bottom part only with  tighter clearance for the locking nub. it is just more raised outwards and not flattened out like the original. it now needs a little force to overcome the locking, but to me the fitment seems adequate. 

The model in the Picture was printed in "PLA - Elegoo Galaxy Peacock Blue", which is an absolute georgeous color for this model. The layer lines are basically invisible.
