Gridfinity Wire spool holder

A stackable Gridfinity holder for wire spool sets you can find on the usual sale websites.

Designed for spools with a diameter of 55mm and a thickness of 21mm max (example of such a spool set). The wire channel has a diameter of 3mm, so 18-20 AWG would be the maximum that should fit (I've tested with 20AWG).
