This is an organizational bin system with a base dimension of 50mm. For example, the 1x3x2 bin is 50 x 150 x 100 mm. It was designed with a 0.6 mm nozzle in mind.
The bins all come with a small tab that works like a handle. At the top of the tab is a recess for a 6mm wide label.
The design was done by me, but it was inspired by the organization bins designed by Alexandre Chappel.
The author marked this model as their own original creation.
