QIDI Tech 1 Part Fan Controller
thingiverse
Unless you're only printing ABS, you'll need this modification to control the speed of your parts fan and significantly improve printed part quality. Print the box, squeeze in the controller, which may require some filing to fit, and wire it between the main board and the fan. I bought my controller from here: https://www.aliexpress.com/item/DC-Motor-Speed-Control-PWM-Controller-6V-30V-5A-13KHz-Digital-Display/32843001132.html?spm=2114.13010708.0.0.3a994c4dSsIrpc You'll need four M3x8mm screws for the box and two M3x15mm and two M3 nuts to attach it to your printer. This modification was inspired by LeePH's postings in QIDI 3D forum on Facebook: https://www.facebook.com/groups/1811744122380955/ It works great for me, so good luck with yours!
