My take on Joe Mike Makes Maker Chip. 
I used K2 Kevin's maker chip kit and instructions to make it. [https://thangs.com/designer/K2_Kevin/3d-model/MakerChip%20%E2%97%89%20Maker%20Chip%20%E2%97%89%20The%20New%20Maker%20Coin-1042339](https://thangs.com/designer/K2_Kevin/3d-model/MakerChip%20%E2%97%89%20Maker%20Chip%20%E2%97%89%20The%20New%20Maker%20Coin-1042339)

I did top layer ironing on the assembly (early attempts I accidentally just did one part of the assembly and it turned out poorly).
I found the QR code worked better if I did it in a different colour than the outer ring.
Filaments I used
Bambu PLA Magenta for the logo
Polymaker PLA White and Black for the chip and Red for the QR code. Any contrasting colour that doesn't blend into the white or black can be used for the QR code
