FlashForge Inventor Side Plate

So one of the minuses of the Inventor is that it holds the spools on the inside of the printer. Perhaps it was a bid to push users toward purchasing FF filament? They do seem to want to make everything as closed source as possible...but if they sell a 3D printer, then isn't it obvious there would be effort to overcome these challenges? :)

Thanks to toolman207 for his work. He made external filament holders that attach to the side of the Inventor. https://www.thingiverse.com/thing:2178642

I really like the vents and entry point, but I wanted an external holder and enclosure for filament as my printing is done in the basement, along with drying clothes, which makes for a humid environment.

The vents and internal brace/frame from toolman207 served as inspiration. They were reconstructed in Fusion360.

The fit of the external vent is fine, perhaps just a touch loose. The internal frame is pretty tight. The edges of the snap in, and there is a very slight inward bow. Th
