Every hospital I've worked in has these little badges that go under your ID so everyone knows if you're a nurse, tech, physician or what have you. I bent mine due to the cardboard nature of the badge and wanted something more substantial so I designed this.
Inverted version isn't as nice given the “holes” are floating an would not be attached.
I made mine in PETG because I leave mine in the car on hot days and prefer it not to warp.
