Elegoo Mars 3 Filter Tray

I have recently been making a series of mods to my Elegoo Mars 3 printer.

I made a heater setup based on the heater made by Martian Wong. I wanted to be able to keep using the official Elegoo air filters so made this cradle/support to hold the filters clear of blocking the air intake.

I used two 3mm threaded inserts to hold it to the Mars frame, but these do not seem to be necessary as it's a very good friction fit.
