Mech Squonker 20700 V3

This is my third Single 20700 Mech Squonker, decided to give a front facing squonk window a go again, connecting up the metal contact for the positive will be a challenge compared to my other designs, but look close and you will see channels/guides, for copper wire or very thin copper sheet to run.

Please consider printing my 510 lock, to protect your atty and mod from firing when you are not using it...
