Qidi Plus4 Spool holder roller

A roller version of the Qidi plus 4 filament holder. I recreated the coupler and remixed into Icy's 70mm “Octa spool roller”I've included a simplified version of just the coupler if you want to test fit - fits perfect for me.Printing:I know Icy suggests vertical printing which is fine. I chose to print the arm horizontally in PETG, with 6 walls and minimal support material
