Sliding card holder

thingiverse

I built a custom ID holder with a sliding mechanism that securely holds my ID cards equipped with magnetic stripes. This invention is essential in my profession, where I frequently need to use these cards. The design features a thumb latch for easy operation. https://youtu.be/R9OwjTFs7FA As of March 2nd, I made some improvements to the spring-loaded mechanism. Initially, the card holder was a bit too loose, so I modified it from 1mm to 0.9mm to keep the ID cards securely in place.
