Badge/Credit card-size holder for lanyards

Update: Fixed incorrect sizes.

I have a credit-card sized badge with a punched lanyard hole. In order to protect it from breaking when wearing it on a lanyard, I made this holder for both protecting and displaying it.

built-in tolerance for the top part, no need to tweak it if your printer prints pieces accurately. The snap-in points shouldstay in place safely. Not long-term tested yet but I'm positive they should last a while.
