This is a 3D printer enclosure originally made by TOPCUDE for the Bambu Lab A1, but it can fit many printers. It has plexiglass walls that enclose the printer to contain fumes and VOCs created by melting filament, and a fan with an exhaust tube to vent them out a window. It could also be used to allow you to print ABS on an open-frame printer.
The interior dimensions are 24.8" x 21.26" x 21.26". It has a built-in spool holder, grommets to allow wires through the walls, and an LED strip. At the top there's a small display that shows the interior temperature, which can be switched between celsius and fahrenheit. There are also holes to allow bowden tubes through the wall, to use the Bambu AMS system. The fan is USB-powered and can be controlled from the buttons on the top. It attaches to a flexible tube that is about 20' long and can be cut to size.
