Poor man's face shield / visor

(Update 200325: The design has now been improved in the following ways:
* less material
* fits a (i3 mk3) print bed (2 beds PET + 1 bed TPU) makes 5 visors.
* better method for fitting the transparent film - just push the side bars onto the film (when loose) and move the bar parallel to the edge to lock it in place)
* There is a film grip also on the top edge
* A bunch of new motives (modifiers) has been added for giving a more human touch (increase in print time is neglectible, only a single filament change required)
I added two .3mf that should explain all needed. Or just print the STLs (1x V, 1x H, 1x låsbit, 2x list)


I was asked by an emergency doctor here in Stockholm if I could quickly design a face shield as they were short on supply (covid19 is to blame here). The design was made the same evening (march 16th), and has now been tested and improved, so I thought I might share it if someone else has a need for it.

The idea was not to make the best visor / face shield
