When printing with PLA, it is often a good idea to keep the glass door or glass lid open to maintain a low chamber temperate. Otherwise, heat creep might cause the extruder to get clogged.

This designs mounts securely onto the plastic lid tab and holds the glass lid open at a slight angle without any play.
