Core One L Removable Advanced Filtration using BlueRolls HEPA filter and fan

This is a remix of @Jason_50683 Advanced Filtration system.   Like him I did not order the Prusa Advanced filter system.   But I am also printing ABS, ASA, and PC filaments that I wanted to filter the air in my space.  So I ordered the BlueRolls fan and HEPA filter from Aliexpress.  But I wanted to be able to remove this when I was printing PETG and PLA to reduce the back pressure and keep the chamber cooler.  Heat Waves suck for 3D printing and I have cats so I can't leave the door open or they think the hotend is something to play with.  

The jury is out as to how effective the system is - but this is a box similar to the official Prusa one I made to mount it to the Core One L.  I have printed a full roll of ABS using this filter and the air quality monitor hs not shown a major increase at about 6 foot away from the printer.   I have printed a lot of the addons to better seal up all the corners and holes in the printer.

Printed in PETG.   Prints without supports. However the four countersinks in the mounting holes on the main box have a sacrificial support layer - clear those out with a drill or hex driver. It is screwed onto the printer with 4 M3 x 10mm (or 12mm) machine screws.   I used 10x5mm magnets that I got from Amazon.

The fan is held in place with the FanMount part using two countersunk M4 screws.

Installation is pretty much follows the official instructions .

The wire that came with the BlueRolls fan was really long, so I leave it hanging out the back of the printer so I have room to move the filter about when I'm not using it.   When I want to use the filter I just attach it and enable it from the control pannel.
