comfortable face shield with size adjustment knob and overhead strip

thingiverse

Face Shield "Employee of the Month" Edition (for 40x20cm Foil) I tried to get my hands on a face shield, but the regular type with overhead fastener and adjustment wheel in the back was completely sold out. Only the ascetic type with forehead bow and backhead strip seemed available. I decided to sacrifice my last PETG spool for a nice shield and found that no "regular type" designs were available. Here is my take on face shields. No other parts are needed except the foil 400x200mm for assembly, though a dab of glue is recommended to firmly fix the forehead piece and around-the-ear pieces to the assembly blocks. The holes can be punched into the foil with a regular European hole puncher, punching one pair of holes in the middle of the edge freehand and using setting "888" for the outer holes. Assembly might be confusing, but I'm working on instructions that will hopefully follow soon. The license is CC0 again, so you're kindly requested to remove the branding from the forehead bow if you decide to make a derived creation with significant changes. 2020-05-15 Update: The version uploaded on 2020-05-14 had a bugged "out_Steckblock_2pcs_Meshed.stl," which I fixed along with the .FCStd file. Sorry for the inconvenience. 2020-05-23 Update: I changed the forehead piece for improved user safety, replacing the old design that might have caused serious injury in case someone slapped your head with a bottle of IPA from the side. The bridge between the shield holding arc and the forehead arc is now diagonal, bending instead of being a pointy hard thing directed towards your head. 2020-05-25 Update: I made the rack piece (out_Zahnstange_2pcs_Meshed.stl) tighter on the gear to prevent it from skipping teeth.
