This thing scares me. Printed one and wired it for two parallel banks of 2 18650s. The holes fit a 22mm varitube 510 Connection, and a e-switch 12mm domed push button with a 17.5mm diameter dome. With 2500mah batteries, this thing lasts FOREVER. I updated it because there were a few things off-center.
