This re-work of Flashforge's design is to save filament as well as turning it into a full dust enclosure. The uploaded new lid uses the glass from an 8x10 picture frame, and the base uses 4 pieces of 4x6 frame glass. These 2 changes alone have already saved about 1kg of filament. Some parts may be modified as the work progresses. The side panel uses 8x10 glass. Simply glue in place with E6000 or similar.
The author remixed this model.
Removed a lot of filler area and replaced with picture frame glass/plexiglass.
