What is it?
It's a quick print fix if you have concerns about the cable tie for the thermistor being too close to the belt.
If you have concerns about the lower screws you can, use a pair of m3x6 to screw into the fan and a pair of m3x8rT with lock nuts to lock cover. That should give you better clerance at the screws.
I printet in Prusament PETG: Galaxy Black upright with organic supports at layer hight 0.1 mm
It's a small print so about 15 min.
The author marked this model as their own original creation.
