Qidi Universal Spool Holder

This is universal spool holder for Qidi-tech printers with luggage handle spool holder. When you tighten up the nut it fixes the filament spool to the aluminium pipe.

In order to use it you will need to replace the two plastic holder on both ends of the aluminum pipe with upgraded bearings version like these:

I press the side handles all the way to the aluminum pipe bearing adapter to create some friction in order to prevent the filament spool spinning too freely, this way I avoid filament unwinding.
