My 15-year old remixed a popular design of a face shield to maximize print bed use of his multiple printers. This is a NO GLUE, snap fit design. We have printed 100 plus and feedback from medical professionals is great and they stay together. This can be used to add color to the prints, use old filament roles lying around, and works great with PETG and PLA. Smaller printers can now participate in the global pandemic help.
Standard setings on the MK3s for Generic PETG or PLA worked fine with 0.30 adn 0.20 speed settings.
