Tevo Black Widow Spool holder no hardware needed

This Spool holder is designed to hang 1kg spools with no mounting hardware needed and the profile hooks into the channel of the Black Widow frame while the weight over the back holds it in place.

They are designed to take 16mm dowel or you could print your own 16mm x 60mm interlocking shafts to suit the length you need.

These can also be configured to take any thickness spool I've come across by making longer or shorter shafts.
