Face Shields sized for Prusa Mini

Based on the RC2 Prusa design, I created a smaller version that would fit the Prusa Mini and still use the same shield hole pattern + new 3 hole punch version see V3.

I kept it simple for ease of printing.
The m3f has the headband and the bottom shield reinforcement (the bottom reinforcement is the same as the one provided by Prusa).
And the STL is provided as well for just the headband.

New 3mf file added for a 3 hole variation.
Another 3mf file (v3) added for more comfortable 3 hole variation
-- v3_6 has now replaced v3: slimmer design while keeping forehead rest for comfort, new notches to tuck shield plastic into. We stopped printing the bottom reinforcement for now, but you can add it it back from Prusa's design if needed.
--v3_9 is available with some minor changes
--v4_0 - Re-modeled to clean up the CAD while keeping all the great features. slimmed down a little more from the previous version.
--v4_4 is now available!! - some minor changes to reduce the amount of material used. With a 0.3 layer height with a 0.4 nozzle I'm printing it in less than an hour.

-- Top Visor Shield templates (PNG, DXF) added (PNG can be printed with specific settings. I told my printer the paper size was A4, photo size was full page, actually printed on 8.5"x11" paper). The visor is put on the headband first then the clear plastic shield is added over the top.
