If you like to use active carbon filter mat, just cut piece in dimensions of 125x85mm from max. 10mm thick ACF mat and place it inside the sealing gasket of the filter. The mat will stay in place between the bracket and HEPA-filter. 

• Printed with PETG (Elegoo PETG Pro)
• Layers: 0.2mm @ 0.4mm nozzle
• Infill: Gyroid / 20%
• Perimeters: 4 - aiming for better stiffness and making walls around srewholes a bit tougher.
• No supports or brim needed for bracket.
• Latches printed sideways, you will need two pieces of them. 5mm brim around.

Fixing:

• Bracket will be fixed with 4pcs. of M3x8mm to the original holes in the back plate. (I used Core One's M3x8rT spare screws)
• Latches will be hinged with 2pcs. of M3x18 screws. Screw will tap itself to the opposite side of the hinge piece. (I used Core One's M3x18 spare screws)

Whole assembly will protrude only less than 35mm from the back plate. Changing the filter takes only 3-5 seconds and no tools needed.
