Awesome project! It's simple yet so much fun. I had no problems with the 3D printing. All the parts fit perfectly and assembly was smooth. I had some problems with the RC522 'flapping,' (tag constantly connecting/disconnecting). This is likely because of the low-quality module I got from aliexpress. However I fixed the problem on the software side with a 2s delayed_off filter. I used the esp32 c3 super mini and the rc522.
