I have designed this awesome organizing system that is circular in design. It is designed to be fully modular and can fit as many cubbies as you can print and assemble. It can be endless! You can organize anything in your office, shop, etc. The cubbies are about 90 mm in diameter (3.5 inches or so) but can be scaled to be larger or smaller as needed. I have included two types of circular drawers (which are on rails so they stay in place!) -- One with a divider and one without a divider. Please see the pictures for detail. Each cubby interlocks with its neighbor and even has 4 mm thru holes so you can mount it on the wall. It is very versitile and should be easy to assemble and use. Each piece is deisnged to be printed with either resin or FDM printers and should have no issues with things like overhangs. I would prin the cubbies on their backside (opening side up) and the drawers face down so that you can use the curvature to your advantage and end up with very nice surfaces.

Please let me know if you have any questions, enjoy!
