Small storage containers that can be closed with the lid of an old pringles can (Only tested with cans from Germany. Not sure if they are the same in every part of the world).

The container are either 25mm or 50mm high, and have one, two, three or four compartments. The Fusion360 file is also attached if you want to create your own. If you don't have Fusion360, just leave a comment with your wish and I can probably do this for you :)

Perfect use for old snippets of filament. The 25mm container are ~22g and the 50mm ones are ~40g.
