Franco14's Maker Coin Cache

This is my friendFranco14's maker coin, but I've added a little secret to it! I've a little hidden compartment to the back of it to hide a folded piece of paper with a secret code, a Micro SD card containing evidence, or anything else that can fit in a flat 1mm space! This method of hidden compartments was inspired from an actual coin that was used by KGB agents during the Cold War using a pin to open up the coin!

Also, please do check out my friend Franco14's thingiverse page for the original maker coin, the newer version of that coin, and a lot of other cool things.


PRINTING TIPS

You may need to sand down certain places around the inside of the hidden compartment in order to make the back part fit snugly. You may also need to use a sewing needle to widen/clear debris from the inside of the pin hole. NOTE: Use a thin paperclip to open the compartment and the back end SHOULD pop off/out. DON'T use a sharp needle to open it for it may puncture through the back end, rendering
