Got a free toolbox from a coworker since 2 of the drawers didn't lock shut with the lid closed. You have to drill out 6 rivets and the top shelf comes out. I replaced the rivets with M3 bolts, washers, and lock nuts.

Due to the nature of 3D printing, a number of adjustments were made to improve printability but some support will still be needed. I recommend printing the model on its side for maximum strength.
