Print-in-place hinged glass top prop for venting the printer. Gives a wide opening to let out hot air to avoid heat creep and clogs when printing PLA and other plastics that does not like too much heat.
After some experimenting I found that just opening the glass top a few centimeters still trapped too much hot air inside, so I designed this to open quite wide and reduce temperature 3-4C degrees more.
