Air Filter / Cleaner

This is my first attempt to create a complex part.

The part has been designed to filter the air from an enclosed 3d printer, to improve the air quality and smell. You need 2x 140 mm fan I suggest going for a high-pressure fan to force the air through the filter better. I went with a 2x Noctua NF-A14 industrialPPC-3000 PWM. For the filter itself its meant to house a Rolfstone HEPA 13 Air filter with 3 layer active carbon filter.

You need to print the following parts to complete the design:
1x AirCleaner Part 1
1x AirCleaner Part 2
1x AirCleaner Part 3
