Modular Stackable Spool Containers

To assemble a single-cell box, simply print the “Bottom + Rim + Cap”. For each additional cell you want to add, print the corresponding “Rim + Connector”. If you need a deeper cell, you can print the “Extension” part and stack two or more spools together. I've added these as print profiles so you don't have to do it manually.

This design features a tight press-fit connection, so no glue is required. If you encounter difficulty fitting the parts, try cleaning the spool edges and gently rotating the spool as you press it into place.

Note: Tested with Creality Hyper PLA spools.

Attention: I would suggest you to measure your spools before printing if you will use other spools. Here are the measurements:

Outer diameter = 89.2 mm

Inner diameter = 80mm
