This face shield frame requires only an additional clear sheet, such as a US-standard 8.5x11" letter sheet. The standard 3-hole punch spacing of 4.25 is used to attach it to the frame.
Reference older model for an included punch template.
Parts are modeled to snap together, with slight outward draft of the connectors. This requires some precision in printing, but they perform well from my Prusa i3.
Print in PETG. These require some flexibility and durability.
Comments and suggestions for improvement are welcome.
Revision 19:
Slight increase in the pin diameter (+30 um) of the adjustment band, to improve operation. Update recommended.
