badge holder for arm strap

thingiverse

I designed a custom badge holder for my arm, modifying an existing lanyard I had on hand. To attach it securely, I considered cutting the elastic out of an old pair of underwear and simply tying and sewing it into place. However, before making any final cuts, I decided to stop the printing process midway so that I could insert a credit card into the space, ensuring that when the overhang was complete, it wouldn't crush the slot and make it impossible to fit a card in afterwards.
