To have a facemask dry out in the car effectively, it may ideally be suspended.
The best way to do that for car driving situations where curves occur, and, where the front seat and middle console are occupied by (clean) passengers, may be to put them behind the front seats, if there are no passengers in the back seats.
Thus I built these clip-on mask mounts. The dimensions are for a Subaru Outback 2018 - but with little effort, this can be adapted to different dimensions.
There should be two STL files (almost the same, maybe version 7 is a tad more refined) and a JPG image to see how it is installed. Update July 2021 - Version 8 of the 3D models published here (hrm8_rigid.stl) has been designed and tested to break less often when mounted and in use.
