Remixed from https://www.thingiverse.com/thing:5100822 but much stronger. I have a case missing many of the internal parts and found this one. When I first printed it, it worked but broken when attempting to use it with any cards. Its been thickened up and is now a lot stronger. Ive been using it for nearly 6 months now and its been great.
