Small case for the elechouse PN532 NFC RFID Module v3. Based off of but not remixed from aix150's design. Mine is for a lock, which is why I created the original with a lock design on the lid. The base also has an inset portion for the thick mounting tape I used to attach it to the door. I removed those features to make the plain versions for general use and then added lid versions in case you're using SPI or if you have both sets of header pins attached.
Compared to the original, this version flips the board to put the connector near the base and uses two 8mm M3 screws to attach everything together. It's about as small as it can get at ~11mm tall (plus screwheads) with 1.6mm walls and 1.5mm top/bottom thickness.
Printed in PLA at 0.25mm layer height without supports (flip the lid). The non-plain versions have built-in supports to help with bridging. They're attached to the model with walls thin enough that they shouldn't be printed.
The author marked this model as their own original creation.
