Fully 3D Printable Modular Filament Rack

This is a fully 3D printed filament rack that can be printed on any printer with a standard 220 mm bed or larger. The design is modular and can easily be stacked on itself. Print InstructionsMaterialI used PLA with great success but if you plan on making larger racks you may consider PETG or ABS. For most use cases PLA works completely fine though. Infill/StrengthI printed at 10 percent cubic infill with 3 walls but 15 or 20 percent infill would probably be sturdier. SupportI would recommend tree supports for the larger diameter holes otherwise you may have warping on the corners of the overhangs which may cause a layer shift like it did for me. Layer AdhesionI would strongly suggest using 7-10 mm mouse ears when printing the shafts otherwise they will definitely lift and cause problems.
