The snap loop for my building access card kept wearing out and breaking so I made a holder to put the card in that is more durable. I printed this on the Kobra 3 Max Combo using PLA filament. Nozzle temp was 230 and the bed temp was60. Supports are set to yes and the organic tree support gives a clean removal. The fit of the card is snug so it is secure but you could scale the holder 1-3% larger if you don't want as snug a fit. The keyring threaded through the loop at the top will prevent the card from slipping out.
