I wanted to create a shield for covid-19 from scratch to meet the needs that my mother found in the hospital, where the few protections left that were provided were of low quality and bad design, this project of mine implements the possibility of rotating the protection of 90 degrees above the head so as to take a moment of air between a break and the other outside the emergency area covid ...

once printed all the parts you will notice that 3 pieces have been printed the higher one with two ring nuts and the attachment for the elastic is to be used as attachment for the head named (struttura testa) .. and must be kept upwards as it has been studied, the arrow on the model must point upwards, for assembly proceed by taking an elastic band and cutting it into a section that can enter the internal rotation circle after which the semicircle door named "struttura porta pannello" must be inserted, inserted the elastic section inside to make spring effect (the red piece you see in the picture is a piece of elastic used to make spring effect and to make the click of the mask work properly) and inserted by force with a drop of superglue the circle on the cylinder of the panel holder named (blocca struttura pannello), the images will illustrate and remove any doubt .. I think that today is the best and most comfortable shield against the covdi-19 simple and comfortable... sorry for my bad english but i'm italian .. happy printing...
Ps : upload a Gcode only for Mk3s.

added a simple safety clip to prevent the plastic from escaping the shield (clip ferma visiera)
