Wire shelf hanging spool holder for Filler spool holder

This is a hanging spool holder for the Filler customizable spool holder system. It has been designed to work with wire rack shelving with 30mm spacing between the wires. This was a first try and is not perfect but it holds the Filler very securely, was easy to snap on to the wire shelf and slide into position.

The spool in this position is perfect for my Ender 3. Obviously your mileage may vary depending on your shelf and printer setup.
