This is a remix using the Tesla Model 3 vent holes to hang up masks on the side, off of the dashboard.

The tolerance is 0.2mm, so you may have to do some sanding, slicing, or chemical reduction post-print.

Suggest that you print in a filament that can withstand temperatures that are common inside a vehicle. I printed in PETG.
