QIDI Plus 4 Top Cover Vent

This model includes 4 objects which can be placed on top of the printer in the four corners.  You can then place the glass back on top and safely print PLA and other low-temp filaments without the risk of heat creep clogging your nozzle, while keeping dust from falling onto your build plate.

You can either print the STEP file, or all four STLs.   Supports are required in some orientations.  I printed them flat as they are in the STEP file, since I wanted the sides and top to be very clean, which they were.
