# Aegis 2 ## Face Shield for COVID-19 #####This is the result of my continued search for the optimal 3D printed face shield. I wanted to help provide a design that can be mass produced to help fight the ongoing COVID-19 pandemic. #####The Aegis 1 had a very good reception and had been printed in huge volumes. Continuing on that foundation, this version focuses more on comfort and extended wear. It has features requested by the community and front liners. #####This is the version 2 of the Aegis design. This one is built from the ground up. It still has the features of the original. The main difference is *comfort* with an option of 3 mounting systems, aiming to eliminate the need for elastics. #####Please feel free to contact me directly via Facebook, I know many who visit Thingiverse doesn't have or are having difficulties creating accounts. I'll be glad to help out with printing and suggestions. ##Aegis 1 available here: https://www.thingiverse.com/thing:4238890 ##**Updates:** **April 27, 2020** - Uploaded your favorite *aegis-max-thicc*, this is for people using large layer heights and with big nozzles. This was requested by Sir Capinpin, thank you for the feedback sir. Sorry for the long delay, got really busy with work and printing. **April 19, 2020** - Refreshed the 'aegis-fold' design. The previous upload had the wrong tension. I've also moved the hinge away from the temples, making it a bit uglier, but more comfortable! - Added 'aegis-fold-loose-fit' this has less pressure on the temples, depending on the head. - You can scale up the the models to fit the head sit and adjust comfort. **April 19, 2020** - Tip: you can use the Aegis Flex without the clipon-temples and even use the Aegis 1 hook. Use a rubber band same as with Aegis 1. - For better fit, if there is pressure on the temple areas, you can scale the print by 1-5% or more depending on target head size. Each increment will have noticeable effect to change the pressure. Sorry, I had only my head to test on :( **April 18, 2020** - I think I made a mistake with the *aegis-fold* model, it might be too tight for most heads! I have several versions with varying head tension, and uploaded the wrong one. I'm currently verifying if I got the right one, I'll upload the correct one today. You can salvage the print if its too tight by using a hot blower, hair dryer, or lighter to adjust the temple if PLA. Scaling it a bit will also help with fit with the current model. ##**Instruction Manual** #####Please check out the instruction manual here: ###[Aegis Face Shield Manual](https://docs.google.com/presentation/d/1k7t3c5iVB8czOETjJBckdMjMNuYY97rHA7rF7egEBzE/edit?usp=sharing) #####*Please note that this is editable, please download a copy and edit for localizing to your language* ##**Printing Notes** - To achieve around **45-1 hr minutes print time on very good quality** I calibrated the design to be printed with these settings: 0.3 Layer Height, **0.8 Extrusion Width / Line Width (very important! 50% savings in print time)**, on a 0.4 Nozzle. I've also tweaked the extrusion multiplier for the top/bottom layers to around 130 percent, which assured good seal of the hood. - A 1KG roll of filament should produce around 34 Face Shields. ##**Models Versions** - *aegis-max* - full length temples. can be used without elastics. - *aegis-fold* - foldable temples, can print without supports. small footprint in print bed. - *aegis-flex* - can use printable clip-on temples, along with a hook. so far the most flexible and comfortable option, tension can be adjusted by tilting temples. ##**Credits** - Face Shield Mount Design by **HanochH** (Aegis 1) - Hook by **LadyLibertyHK** (Aegis 1 & 2) ## **Release Notes** **April 16 2020** - Added **aegis-max.stl**, **aegis-fold.stl**, and **aegis-flex.stl** face shields. - Added **aegis-flex-clipon-temples.stl** and **aegis-flex-hook.stl** for the **aegis-flex.stl** ## **Thing Files Guide** - *aegis-max* - full length temples. can be used without elastics. - *aegis-fold* - foldable temples, can print without supports. can fit more in printbed. - *aegis-flex* - can use printable clip-on temples, along with a hook. so far the most flexible and comfortable option, tension can be adjusted by tilting temples. - *aegis-flex-clipon-temples* - temples that can be clipped on used with a hook or elastics. - *aegis-flex-hook* - used with clipon-temples for provide tension and support. ##**Objectives** 1. Comfortable for extended wear, our medical front liners are tired need to help them as much as we can 2. Non-reliant on using elastics, which can be scarce in some areas 3. Low cost that can be made and given to medical front liners 4. Fast printing, we need to be able to product a lot in a short amount of time 5. Printable on a small 3D printer bed, need to leverage all available printers out there 6. Easy to assemble and no post processing needed, time is valuable the faster we make the more lives potentially saved ##**Materials for construction:** * 1 pc Acetate Sheet (A4) or any plastic that is rigid (100 - 300 microns tested) * 1 3D Printed Face Shield Frame ##**Printing Tips** This can easily be printed, but since it uses interlocking parts and thin level layers I suggest printing on PLA for flexibility and avoid warping. I've also tested the designs in ABS, and found them more durable. Just address the bed adhession, and it should come out good. With my settings I can complete this in around 45 mins -1 hour on a .4 nozzle. Each printer and slicer are different, you need to tweak to get your target print time. Please perform some calibration before print, I can share my settings using Simplify 3D on a FFCP. And CR10-V2 using Cura. Other Important Settings using Simplify3D/Cura or other slicers: ####**Layers** - 0.30 - Layer Height - 3 - Top Solid Layer - 2 - Bottom Solid Layer - 1 - Outline / Perimeter Shells ####**Speed** - 70 mm/s - Default Printing Speed - 80 mm/s - X/Y Axis Movement Speed - 60% - Outline Underspeed - 80% - Infill Underspeed ####**Extruder** - 0.40 mm - Nozzle Diameter - 1.30 - Extrusion Multiplier (Simplify3D) - 130% Top/Bottom Extrusion Multiplier (Cura) - 0.80 - Extrusion Width - IMPORTANT!!! Makes printing 2x faster than 0.40! ## **P.S.** ### Fight hard against COVID-19! ### Regards from the Philippines.
