Oh, and probably a piece of wire or two, some solder, and a soldering iron. And two 3.7v batteries CR123A or 16340 Lithium. And a screwdriver. ;-) Check your switch to make sure it's like mine, but the two contacts nearest the hinge point are what I used to make the connection when the lever is pressed down. Use a piece of filament as the hinge pin. Drill or ream out the holes if needed, then melt the ends to keep it from working itself out. The new screw hinge option is designed for M2x8mm socket head cap screws, but something close in size would probably work fine, so long as the lever arm is secure and rotates easily. IMPORTANT NOTE: if you have a 16340 unprotected, or a CR123A, you have to print 2x 16340_battery_case_normal if you have a 16340 protected (it is 1.6mm long then the unprotected version), you have to print 2x 16340_battery_case_long * The links provided for the 16340 battery (Amazon / Aliexpress), is referred to a protected version
