This is a remix of the Voron 2.4 exhaust filter housing. I modified it so it would fit this canister for a Roomba 8xx/9xx HEPA filter. The original housing just isn't deep enough.
Getting the canister in is easy, to get it out you may have to push from the inside of the printer through the exhaust filter grill.
Print in this orientation:
I've printed this in ASA with a 0.6 mm nozzle and 0.3 mm layer height. For the large overhang you may want to use supports. To prevent warping you may want to add a brim/mouse ears.
I've added a Fusion 360 file if you want to modify this further. This is based on the Voron 2.4 assembly from the Voron Design Github.
The author remixed this model.
