Universal A4 Visor - Face Shield
Project under development.
V2 changes : Optimized to reduce the material use, added "no slip" strips to hold the clips in place, optimized for faster printing ( removed ventilation holes from the part touching the forehead), added T shape buttonhole elastic holder.
This project was made to help medical staff. 3D printing enthusiasts around the world came together to help the people from the first line, in this battle against COVID-19.
The visor holder parts are optimized to use A4 clear sheets up to 0.5mm thickness. It was successfully tested with thin clear foils used for Overhead Projectors ( Used: https://www.ebay.co.uk/itm/Overhead-Projector-OHP-Film-Acetate-Clear-A4-For-Laser-Printer-60-Sheets-Hartw/112572030652) and with A4 PETG sheet 0.5mm thick.
Features:
Slim design - 3 holders can be printed in the same time on a small printer like Ender 3;
Compatible with any A4 clear sheet up to 0.5mm thick;
Sheets are held in place by clips; Optimized to avoid clips from slipping; Strong grip;
Optimized for buttonhole elastic bands, but can be used with any elastic bands;
Screw holes for extra security if needed;
Printing instructions: From my experience, the number of walls are more important than any infill percentage. To print this, I have used 0.4mm nozzle, 3 bottom layers, 4 top layers, 4 walls, 0% infill. The part came out very strong and flexible.
If you have any suggestions, please leave a comment below.
I have also created a Facebook group called "Medical 3D Printing & Designing" to bring together people wanting to help. Anyone welcomed to join - https://www.facebook.com/groups/2585143625099765
