As suggested in one of the comments, I’ve reversed the order of the HEPA and carbon filters. I also added about 2mm of extra space for the HEPA filter, since mine didn’t fit properly.

I wanted to create a chute for my printer's waste while still keeping the printer as close to the wall as the power cord and AMS hub allow. To achieve this, I designed a system that redirects the printer waste into the drawer beneath it.

I placed my printer on a cabinet where it just barely fits. After switching to anti-vibration feet, I was concerned it might slip off while wobbling and dissipating vibrations. To prevent that, I created a sort of hidden physical limit using 8mm rods that hold the printer securely in place. The assembly requires a 8mm collar with a set screw, some screws and 8mm steel rods.
