Warning! ground before touching

thingiverse

I recently fried a BTT SKR Mini e3 V2 by clearing the hot end just as a print was beginning. Apparently I had built up a charge and I was discharged through my nozzle. The immediate result was a bricked blue screen on the display and the inability to operate the printer. I was not able to flash the bootloader or firmware (not sure if my own errors or the main board was toast but the 5V and 3.3V were good!). Anyway, I ended up buying another BTT SKR Mini e3 V2 which solved my problem. First thing I did with my newly operational printer was create and print this warning to avoid ever making this mistake again! Hopefully you can benefit from my experience! Note: This design is a tight fit to avoid it moving under printer vibrations.
