I decided to make another version of my stun gun to address some issues. First, I printed it using a PETG filament this time that has a higher melting point than PLA (there was slight melting around the electrodes before). Secondly, I made the cell accessible and replaceable (the rapid drain makes the cells die prematurely, so having the cell be permanently glued inside was a problem). And lastly, I used these really cool pointy bolts that I salvaged as the new electrodes.
