I have Ruuvitag in every room of the house measuring and storing temperature and humidity. I also have several outside in the yard and several in my 3d printers measuring chamber temps etc.
I try to always have CR2477 in stock, but sometimes I just forget to restock and usually then tags start to run out of juice. I don't want to lose even a day's worth of data from any of the tags so I created this adapter to allow me to use super common CR2032 instead.
I printed mine in Sunlu PLA, 100% infill. These can be used 2-3 times before the sides start to crack.
