Here's a quick and simplistic face mask stand that's made for full size facemasks. The default sizing of the stand will fit a mask that fits approximately a 21.5" size head. It is then, a little on the smaller size for masks that are made for someone with larger of a head size, but it should be no problem to size up in your slicer. What I would do, is, import this or your sized mask onto the same plate together, and rotate your mask so that you can size up the stand appropriately. I would also suggest printing this in an infill percentage that is equivalent or more than that of the mask it will display. Hopefully now you can enjoy, and display some of your favorites.
