M5Stack AMG88xx rear magnetic mount

Wanted a small holder for the AMG8833 without opening up the M5stack so this one just holds onto the rear of the M5 with 4 magnets that hold onto the ones in the original battery case. Nothing fancy, I just wanted to protect the somewhat pricey module and not lose it in a drawer so easily.
I used 5mm x 3mm magnets and a quick dab of superglue to hold them in, the square bit fits over the back of the pcb so you can glue that in or use blutak without upsetting the electronics.
