Looking for a simple and minimalistic EDH deck box? Well you are in the right place.

It is designed to hold a 100 card MTG EDH deck with double sleeved cards. It is the same size as a big Ultra pro deckbox. Inner size is 80x70x98 (mm). Walls are 3mm thick.
It may need some cleaning on the sides and entry point of the lid. You may also need to clip the corners of the lid so that it fits all the way in to the insert.

The lid holds in place well in my prints, but if you see it sliding around you can use some layers of tape on the under side of the insert, right where the lid enters it.

Printed on an Ender 3 with a .6mm nozzle, medium to fast settings and a simple PLA fillament. Took 4 hours and about 100g of fillament to print the box and the lid. I recommend rotating the model in your slicer by 45deg on the xy axis so that the overhangs print with long lines instead of zigzags (at least on the first layer). You can also use supports to achieve better results.
