This face shield was designed to be printed quickly and assembled with inexpensive and readily available materials while providing full face protection, comfort and adjustable fit. A fully assembled shield will cost less than $1. This was inspired by many other designs including the 3DVerkstan shield.

Key features:

• Frame is optimized for a 0.4mm or 0.8mm nozzle and can be printed in 60 or 30 minutes respectively
• Frame only uses 28 grams of material so 35 parts can be printed from a 1kg spool of filament
• Frame can be worn as printed or more securely with one or two basic hair elastics and six adjustment locations
• The frame can be stacked with a 0.3 mm offset to print multiple pieces sequentially
• The outer print size is 215mm x 170mm
• The shield is made with an 8 1/2 x 11 inch sheet of write on transparency film
• The six holes in the shield are made with a standard three hole punch using a half inch spacer and punching twice
• A separate top shield can be printed and snapped onto the frame to close the gap above the eyes
• Additional comfort can be achieved by attaching a 3 inch length of insulating foam tape to the brow pad. Guidance is requested for specific type of foam tape that should or shouldn't be used.
• The total cost for a complete shield is $0.87.  $0.66 frame, $0.10 elastics, $0.08 foam, $0.03 transparency film (35 frames per spool at $24/spool, $10/ 200 hair elastics, $13/100 transparency films, $5/17ft of foam)

Materials

28 grams PETG filament

qty (2) standard hair elastics (5 cm diameter)

qty (1) 8 1/2 x 11 clear write on transparency film (11 x 17 can also be used for a longer shield). Transparency film for printers can also be used but it may have a texture and be less clear.

qty (1) insulating foam tape 3 inches long 1/2 inch wide by 1/4 inch thick or similar

Future revisions planned

• make frames stackable without any additional support material
• nest frames to fit on larger build platform such as Tevo Black Widow or Creality CR-10
• add a snap feature to improve connection between frame and cover
• make a version with different pin locations for a vertical 8 1/2 x 11 sheet of film
