Klipper Expander Cover with clearance for the Thermistor terminations as to prevent pinching the connectors when in closed.
this print is really dependent on tollerances so can recemend you slightly scale down the model as i have found it does not shrink the same amount that the frame piece does therefor making the fitment to tight.
it also requires that you have your supports well tuned inorder to print the upper surface well i can recemned really slowing doen your print speed for the top support surface.
The author remixed this model.
the cover door has been expanded out to give clearance to the extra thermistor ports inorder to prevent any kinking or pinching of the thermistor connections aswell as protecting them.
