iPhone Credit Card Case

thingiverse

This clever design lets you conveniently carry just your phone and gym ID, while also featuring a built-in kickstand for GPS usage on your dashboard. To assemble, first print one copy of each part except the sound buttons, requiring two of those. Insert the sound buttons into the bottom case, followed by sliding the phone and mute switch into place. Next, affix the home button to the top case upside down, then sandwich the bottom case onto the top case. Secure with four metric 18-8 stainless steel low head socket cap screws (M3 size, 6mm length, 0.5mm pitch) from McMaster-Carr. Lastly, a bamboo kabob skewer (3.4mm diameter) serves as the pin for attaching the credit card holder's hinge to the bottom case.
