Bentobox v2.0 Carbon Filter Back Pack Mount for Prusa XL with XL Enclosure

Originally, I printed (2) SSX556's BentoBox v2.0 5015 pull-configuration case+shroud carbon filters to use with my Prusa XL printer. This was prior to even having one in my hands. I used them as stand alone filters to aid in cleaning the air. I recently have installed the Prusa XL Enclosure and wanted to find a way to use the (4) 5015 fans that were in them. I modified RickJ19Zeta8's Bento Box XL Tall to find a way to install the bentobox inside the enclosure, but found it was too wide in the pull configuration to clear the print heads with SSX556's BentoBox remix. I saw ViniS' Bentobox v2.0 Pull Vertical orientation for Creality K1/K1C and tried to fit that version of the pull-configuration on top of my modified BentoBox XL Tall. It was still too wide to clear the print heads.

So I decided to find a way to mount it on the outside, taking inspiration from Christophe-P's Rpi 4 Support for Prusa XL. Sandwiching the mount around the hex grid grill at the back of the Prusa XL.

I still wanted a pull-configuration, a sort of vent exhaust filter. I went back to the drawing board and modified ViniS's fan case duct (shortening the height and increasing the width to accommodate the XL enclosure width difference from the Prusa XL - as it is not flush) and incorporated the tapered shape from RickJ19Zeta8's bentobox base. First, I used (4) mounting points but found difficulty in attaching it to the hex grid evenly. I removed the bottom two socket cap screws and found that it mounted securely to the hex grid. I have since updated my vent mount to only have (2) mounting points and changed the u-shaped back plate to a straight bar back plate. The photos posted have (4) mounting points and use the u-shaped back plate, but I only have (2) screws actually installed. 

Install (2) M3x3 brass heat set inserts in the back plate and (4) 6x3mm neodymium magnets in the vent mount.

Installation is easier with two people, I tried to do it alone but with the enclosure bolted on top of the Prusa XL made it very difficult. One person to hold the back plate in place as the second person lines up the vent mount and fastens the two parts together will go much faster.

This mount is compatible with the original BentoBox v2.0 with 4020 fans or any remix that uses the same footprint as the original with 4x2mm or 6x3mm neodymium magnets.

Yes, this file is in multiple pieces. I chopped up 2 designs to make a mash up. I started to merge the multiple parts in 3D builder all the way down to 2 pieces. But as you can see there is degradation/distortion in the quality of the file. I printed mine from the pieces. It prints just fine. I have included an upload of the two piece file just in case, someone prefers to deal with less pieces.
