A toothpick case with a closing mechanism.

Print the case and the lid, and assemble the case by threading a piece of filament through the side and lid holes to function as an axle. Cut the filament slightly shorter than the axle hole before you push it in to make it look tidy.

Print the lid upside down and the case right side up. No support needed.

The samples were printed from PLA with a 0.6 nozzle and 0.2 layers.
