Prometheus Shield Holder

This is the shield holder only:
After extensive investigation I believe it's best to source your own transparent shield covers. Read the section below for more information.
Sourcing your own shield covers:
You can purchase your own covers directly from mybinding.com (right now), or if you need large quantities of refills in the future. Please see the links at the bottom of our shield cover page that will take you directly to the correct products on their site.
More than likely any "report cover" will work so you can purchase them from different sources or try to find them locally; however, clarity can vary quite a bit. I've personally vetted the two options I'm recommending. You'll also need a 3 hole punch, or pay extra to have mybinding.com punch them.
We are providing these shield holders to medical professionals for $5. This covers only the cost of raw materials, not labor. Once the design is validated I will provide the design files to the public so anyone can print this shield holder.
Please only order what you need immediately. We are moving our entire supply every day, so I want to make sure those who need it most have access.
If holders are out of stock, sign up for a stock notification and you'll get an email when we put more on the site. Our production capacity on our single printer is 12 units every 24 hours.
The honor system
These shields are for medical professionals only. They are NOT for civilian use.
If you are a civilian and buy one, that means some medical professional is not getting the equipment they need. Medical professionals include doctors, nurses, Fire & Safety, dental, etc.

There are A LOT of designs out there right now. I looked at all of them to create this design. Primary influences are shields by Markforged, USCF, and Prusa Research. I fixed all of the issues with those shields and optimized for the following:
- Print speed
- Part nesting
- Print stacking
- 3 hole punch compatibility
- assembly speed
This design is also compatible with rubber bands if you don't happen to have a bunch of 1/8" bungee cord sitting around ;)
