Qidi Plus 4 Spool Holder - Bambu Hub

I wanted to use the spring loaded hub from a Bambu AMS Lite on my Qidi Plus 4. I created this model to mount in the stock location and use the green hub to hold the spool and keep tension without having it loose or run out the filament. The spool arm is reverse threaded so it will stay tight when feeding the filament the correct direction. I made it as support free as possible, but the Qidi mount requires 3 small supports. The remainder of the mount prints without any other support.
