BentoBox v2.0 air filter for Qidi x-Smart 3

I couldn’t find a version that fit inside my printer, so I modified the fan base to be 10mm shorter and added a cutout on the right side. I also included a through hole at the back wall to allow mounting the base to the rear of the printer, using an M3x10 bolt. Additionally, I adjusted the holes originally intended for heat-set inserts, allowing M3 bolts to self-thread directly for securing the fans. 

The fans enclosure, the hepa filter, and the carbon cartridge STL files are the same as in the original model https://www.printables.com/model/272525-bentobox-v20-carbon-filter-for-bambu-lab-x1c-enclo
