Keychain Card Guard

thingiverse

I love the convenience of having barcode cards on my keychain, but they never seem to last. After a few months in my pocket, they're usually beaten up and delaminating around the edges. This is an attempt to prevent that. The keychain card guard envelopes the keychain card and protects the edges from fraying. This version will fit a barcode card that is 53.9 mm x 28.4 mm x 0.65 mm, with a 4.4 mm diameter keychain hole. Feel free to remix to fit other cards! I recommend printing with supports, and changing support settings so you have as few as possible. They can be quite hard to remove. I'd love to try printing this with soluble supports in the future.
