This is a .stl i became from Qidi engineers to support the top cover of my X Plus 3, which was deformed due to shipping and permanetly scratching the ptfe tube while printing.
Big thanks to great support from Qidi!
I printed the 2 pices out of PC to get no problems with temperature in the heated chamber.
You may take any heat resistant filament.
