FÖRNUFTIG Filters Holder for Prusa Core One

New filter holder for the Prusa Core One, based on the Ikea FÖRNUFTIG filters (HEPA + charcoal) inspired by Thomas's design of the UPPATVIND filter holder.
Wanted to add the charcoal part, for fumes; so had to design a new enclosure for the larger filters of the FÖRNUFTIG.
Ikea part n° : 194.441.96

Charcoal filter : 37x24x2cm (measured 36.9x23.2cm)
Paper filter : 39x25x2cm (measured 39x25cm)
(2mm added in each direction for the seal)
You dimensions may vary, feel free to contact me if there is a massive difference somehow.

Also made a 10mm spacer, as I can't verify the fit of the filter at the moment. Feel free to ask for another thickness.

Spliced the large parts (base and cover) in 4 parts, allowing it to print basically on every printer. CA glue should work perfectly, but I didn't change the files to accomodate the glue - not sure the bond will be strong enough, testing is needed.

M3x10mm screws for mounting flush with the printer;
M3x20mm screws for mounting with 10mm spacer.

Feel free to hit me up with remarks / issues, I'll do my best to sort it out.
