Summary This box is very deceptive, the threads and perceivable lid are in fact decoys, they are one piece, printed together. The true lid to this container is located at the bottom, and requires an everyday object like a quarter to open. Except it isnt just that easy, the threads for the bottom lid are left handed, meaning Righty-Tightly Lefty-Loosey does not apply. You need to reverse it in fact. Turning the lid to the left tightens it while the right loosens it. Print Settings Printer Brand: RepRap Printer: Prusa i3 Rafts: Doesn't Matter Supports: Yes Resolution: .2mm Infill: 25%
