I really like the original design intent but I wanted it to be more easily removable so I slotted the mounting holes so it can just be lifted off and added magnets to secure it. I prefer the look of hexagon holes so I revised the exhaust grid.
The author remixed this model.
Slotted the mounting holes so the filter can be lifted off the screws.
Added magnet pockets (5mm x 5mm round)
Changed the exhaust “grid” to hexagon holes
