Print one Belt Box for each belt you want to store, and then a single lid to complete the stack.
The box file is split into parts so that you can use a filament change to add rings to match the belt's colour. The Lid provided is blank ready for customisation with a name, or eg I modified mine with the local school's logo.
No supports needed. Recommend 10% infill, though it doesn't really matter as it's mostly walls.
To finish them with a nice effect, I recommend a Concentric Rings top/bottom surface pattern.
The author marked this model as their own original creation.
