This design supports 3-hole punch system for use with sheets. Visor features covered top and tight tension across 8.5x11in sheet. Tested shield clearance with safety goggles and face mask.
Full 8.5x11in sheet is used with exception of trimming corners near chin area. 3-hole punch applied to both sides. Visor and bottom holder use same 3-hole punch (2 x 4.25in – 0.25in hole diameter).
Curls on the ends of arm holds a rubber band. Arms are thin to minimize head coverage and use less material for faster print times.
8.5x11in sheets of transparency film was used for test fitting. A minimum of 0.4mm for material thickness has been medically approved, only use thinner sheets for test fitting purposes.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
