Description

Designed for 3D printing and to print fast with no supports. Thermal shrinkage compensation to ease the assembly and alignment of parts. Currently in use at hospitals in Hawaii. Designed to print as only walls and a floor. Set slicer wall count to at least 2 walls. Should print with 4 walls thick with a .4 or .35 mm nozzle. Infill setting does not matter. One set uses 34 grams of PLA material. This can be printed without supports(except for clip file which needs supports for integrated rivet). Does print successfully without a skirt but one may be used if bed adhesion is an issue. Do not print rivets with a skirt due to difficulty removing the skirt. The face shield hole pattern matches a standard 3 hole punch. PET, PC, PVC and other clear plastics may be used. Standard size 8.5"x11" clear binder covers make cheap easy to source face shields. 18 inches of half-inch elastic is used to make the band. I have provided the file with no logo because I would not like that to prevent you from helping out with tour printer or expertise. We prefer to use the combination of the frame, retainer, and three rivets to build a shield. Electrical tape may be placed over the rivets to seal the front. The clip file eliminates this need but it is harder to nest multiple models and needs to be printed with supports. This file is provided under the Creative Commons license CC BY-SA
