About this 3D model
ENG: I designed a Coin which fits an RFID-Chip inside. I use it to send an automated message with Apple Shortcuts, but of course you are free to use anything else. To add the RFID-Chip inside the Model, I recommend pausing the print at Layer 12 if you are using the STL. I used these RFID-Chips from Amazon (NO Affiliate Link!!:) www.amazon.de/dp/B09TRDP173 DE: I have designed a quick chip that has space for an RFID-Chip. I use it with Apple Shortcuts to send an automatic message when I hold the Coin to my iPhone. To insert the RFID-Chip I recommend pausing the print at Layer 12 if you are using the .stl file.
