This remix includes a variation of the Support Pin from the original upload that allows you to screw a PTFE connector directly on to the spool holder. I'm using this as a way to quickly connect and disconnect my hanging filament to my printer.

This is used in conjunction with https://www.printables.com/model/32368-join-ptfe-tubes-together-magnetically to make filament changes quicker.
