Modular Solder Spool Holder

This design allows you to set up an array of different solder rolls at your soldering station. The parts link together laterally and stack vertically to create any configuration you want.

This design can accommodate solder rolls up to 66mm in diameter and up to 84mm in width. Inner diameter needs to be greater than 19mm.

You will need a rod of 8mm x 100mm to run through the center. The below part will work, or you can 3D print a rod (model included). Using steel is stronger, but a 3D printed rod works fine.
