Aegis Face Shield for COVID-19

thingiverse

This appears to be a documentation for a 3D printed face shield frame, specifically designed for medical front liners during the COVID-19 pandemic. Here's a summary of the document: **Design Objectives:** 1. Low cost and easy production 2. Fast printing time to produce many units quickly 3. Printable on small 3D printer beds to leverage available resources 4. Easy assembly with no post-processing required 5. Comfortable for extended wear **Changes to Optimize Printing:** 1. Enclosed top to prevent droplets from entering the eyes 2. Modified overall height and shape 3. Removed forehead support to lower profile 4. Shortened temple (ear part) for smaller print beds 5. Removed center rib for less print movement 6. Reduced weight from 22 grams to 15 grams **Changes Based on Community Feedback:** 1. Added a "temple" version with an ear portion for better security and using one less rubber band 2. Created a "thicc" version for easier printing in bigger nozzles 3. Revised the hook design for durability and secure rubber bands **Features:** 1. Completely closed top to prevent droplets from entering the eyes 2. Semi-flexible for comfortable fit 3. Adjustable tension via back hook 4. Very light weight (15 grams estimated without Acetate) 5. Modified thickness on certain parts to save material cost and print time **Materials Required:** 1. 1 pc Acetate Sheet (A4) or any rigid plastic 2. 2 pcs Rubber Bands / 1 pc for the "temple" version 3. 1 3D Printed Face Shield Frame 4. 1 3D Printed Hook for Rubber Band (credits to LadyLiberty) **Printing Tips:** 1. Print on PLA for flexibility and avoid warping 2. Use a layer height of 0.30 mm and top/bottom solid layers of 2 3. Set printing speed to 70 mm/s, X/Y axis movement speed to 80 mm/s, and outline/infll underspeeds to 60%/80% 4. Use an extruder diameter of 0.40 mm, extrusion multiplier of 1.00, and extrusion width of 0.80 (important for faster printing) **P.S.:** The author thanks the community for their feedback and support in creating this design. They encourage everyone to fight hard against COVID-19 and express their appreciation from the Philippines.
