To successfully print PLA with enclosure, Sovol recommends removing part of the upper glass and keeping the door open. 

I had a problem with the doors, where they just wouldn't stay fully open, so I designed this door stop. It latches to screw holes and door hinges, and does its job.

Preferably print in something more resistant than PLA, I printed mine with ABS, 3 walls, 20% Adaptive cubic infill.

Print two parts, one mirrored in X axis.
