WEBPAGE STILL UNDER CONSTRUCTION. Don't have access to a 3D Printer? Try this DIY version
DISCLAIMER: I am not a medical professional nor do I design in medical manufacturing. I am sharing this design because I believe it will be helpful for non-medical essential workers who still need equipment. A faceshield, when used with a face mask, can greatly increase your level of protection. Use at your own risk.
DESPITE THE UPDATE PLEASE STILL REFER TO THE REST OF THIS WEBPAGE FOR REFERENCE !

Why design this?
Why design this?
There have been alot of great 3D printed designs generated for the medical industry in the last couple of months, which are excellent. However they take a while to create (2-3 hours just for printing), and have to adhere to strict medical design needs (as they should!). Many of these designs aren't producible to scale for all of our non-medical, yet essential workers in our grocery stores, gas stations, restaurants, sanitation, etc.
What this design does differently
What this design does differently
- Using a baseball cap cuts the need to 3D print a band like structure, reducing overall print time to 21 mins (3 clips) per shield from 2-3 hours
- Baseball caps are accessible, customizable in terms of sizing, and are overall more comfortable to wear
- printed clips can be added, removed, or repositioned easily to account for a variety of sizes of already made shields or DIY shields
Excellent RC1 design for medical use by Prusa, that unfortunately requires significant print time
This design only requires three small clips be printed rather than entire headband
Comparison of ver. 1 clip (middle) to everyday objects: jumbo binder clip and US quarter. Ver 3 is half the size.

1. Sand Down Print
Only do this if you are having trouble with your clip being a little loose1. Sand Down Print
- We want to remove any smoothness from the surfaces touching the cap. Sanding those areas very lightly will make the areas rougher and increase the clip's gripping power.
- Using sand paper (fine grit) or file (nail file will do) lightly sand down the teeth and inner bed of the clip
- Don't over do it, too much sanding may cause the canal opening to get larger and decrease grip strength
2. Add Clips to Cap
2. Add Clips to Cap
- You will want to use a flat-billed cap
- add clips so that the teeth are on top of the bill. Push clips all the way back onto the bill
- we recommend using 3 clips, but add more if you want!
- the clips are movable so adjust them to align with the holes in your pre-made shield, or you came make your own DIY shield following the instructions down below.
3. Attach your Shield
3. Attach your Shield
- Attach your shield using the provided holes so that the shield hangs off one of the hanger hooks.
- If you are using a larger pre made shield, you will most likely use the first hook closest to the outside of the brim
- If you are using smaller DIY materials like 8.5 x 11 transparencies, then use the other two the inset hooks to get more coverage. Adjust as you see fit.
- Congrats! Your Done! Don't forget to review the maintenance section further below.

Material Considerations
Material Considerations
Consider the following for choosing DIY material for shields:
Size
Size
- the ideal sheet size of material to fit around the outside brim is around 15" wide by 9-10" high depending on the length of your neck. This is not a regular sheet size like 8.5x11 which can make finding materials a bit odd.
- You can use a smaller piece of material, such as these 9x12 heavy duty job ticket holders found at staples, but depending on the size of your brim, it may not give you fill side coverage.
- UPDATE: Version 2 accommodates 8.5 x 11 material
Ver1 with 9x12 material provides full frontal coverage, but only partial side coverage, Ver2 provides more side coverage by using inset hooks
Clarity
Clarity
- Many of the DIY materials you might consider, like document covers, thick mylar flim, etc, are "clear" but not fully transparent, Many times you can still see through these materials, but not quite as sharply. You will have to decide how accurate your vision needs to be for the task at hand.

Durability
Durability
- Often times the clearer a plastic material, the thinner it is, which may be more susceptible to wear and tear due to time, sanitizing, and environmental conditions. Avoid anything thinner than 3mil thick.
Very clear document sleeve but also very flimsy and not durable

Making the Shield
If you are making alot of these, I recommend a 1/4 hole punch, which can be purchased at a pharmacy, office store, or online. Its faster and its easier to use. If not, watch the corresponding video, to see how you can use a hobby/xacto knife to cut a cross hair where you want your opening to go. Making the Shield
1. Reinforce Area With Tape
1. Reinforce Area With Tape
Your shield will develop alot of wear and tear if you use it every day. one way we can reinforce the hole area.
- put your material down in landscape orientation.
- cut small pieces of a thick tape (duct(k) or gaffers) and apply them to area you want to make your holes: left, middle, and right along the top of your material.
2. Make your holes
2. Make your holes
Take your hole puncher and punch three holes.
If you dont' have a hole punch, use and hobby knife to cut a cross "+" where you want to make your holes- on the left and right edges, don't make the holes too close the corner, bring them in a little closer to the middle.
- make your holes about 1/8" to 1/4" from the top of your material.
- If you screw up, thats ok! because the clips can be repositioned, our holes can go almost anywhere! Just try again
- CONGRATS! ATTACH IT TO YOUR CAP AND YOUR DONE!
Optional: - curve the bottom corners of your shield using a pair of scissors
Maintenance
Maintenance
Remember to wear a face mask when using a faces shield
Cap
Cap
- should be washed/sanitized regularly, especially if you are sweating while using this shield
- Recommend 3 caps on rotation, so you always have a clean one
Tip: You can add a button to your caps to reduce ear strain from elastic face masks!
3D printed Clips
3D printed Clips
- Never leave in a car or heated area. They may warp in extreme heat
- If your clips start loosing grip over time, cover the teeth with a thin layer of hot glue
- Let cool completely before you attach clips back to your cap
- Can be disinfected using lysol or other cleaning agent
Shields
Shields
- should be washed and sanitized regularly
- Remove them from cap first and lay flat to wash
- try not to use hard sponge as it may scratch the material and reduce clarity
- The holes you made will give out at some point from wear and tear. that is ok, just make new holes and move your clips accordingly.
