Voodoo Face Shield
During the beginning of the Corona pandemic in 2020 when protection gear like face shields were in high demand and short supply, I used my "voodoo" 3D-printing technique I also used for the Garberobe to help out.
Prusa Research published models for a face shield that became the de facto standard with many compatible variants from the community. It took about 3 hours to print but there were several slim versions with reduced print times. With a 1 mm nozzle and 0.5 mm layer height and in one go without travelling I could print in 18 minutes what others printed in 1½ hours.
