This is a minimalist and simple, but very functional little treasure chest. I made it with a strong hinge and interlocking mechanism so it can be closed rather nicely.

It can be used to store one or two miniatures (depending on their size), a full set of dice, board game pieces, coins, printer poop, or any other treasures you may want to protect. 

To achieve maximum smoothness and symmetry, I separated the lid into two parts to allow for it to print vertically without internal supports.

To assemble the lid, you  simply need to align the pieces so the notches match, and snap the side wall into place: no glue needed! The seam is pretty well hidden too. The two pins for the hinge will also just slot in and shouldn't require glue; but if it's loose, a bit of glue on the  heads of the pins should keep them in place.

If the lid refuses to lock or close, make sure there's no support debris around it. 

The model scales up nicely to 1.5 and 2 times the size without any modifications, but at those sizes I'd recommend gluing the hinge pins in place since they become looser with size.

If you print it at higher scales please disable the “On Build Plate Only” option on the supports tab.

Update 03/29/25:

Added a new print profile  with the lid on a separate plate for people who want to use shinier filaments, since at least on my printer, the finish on silk and glossier colors changes when the body of the chest finishes printing and the lid continues alones. 

With the separate plates, the lid can just print on its own.

Update 03/21/25:

I've been experimenting with Silk and other glossier finish filaments, and I've found out that you can maintain a more consistent gloss and color across the lid if you separate the print into two bed plates, one for the lid and one for the body and pins.

For silks I'll also recommend using slower speed settings to improve overall appearance and strength.
