Storage box system. Very flexible

thingiverse

A modular storage system that can be stacked on top of each other. To print the largest BoxHolder, you'll need a large 3D printer, but smaller ones can be printed down to 3x3, which is about 15x15 cm. The smallest box measures 5x5cm and stands at 5cm tall. It grows in modules of 5x5cm, so the next size up is 5x10cm, and so on. Small boxes can fit inside larger BoxHolders, and these holders come in various sizes. A great benefit of this system is that you can remove individual boxes from their holder when needed, giving you quick access to your stored items. UPDATE June 2nd, 2020: VaseMode Boxes for faster printing. Print in VaseMode and the boxes can be printed much quicker, with a generally nicer finish.
