Iron Man hand cannon

thingiverse

I made the very elegantly designed Arc Reactor by MishaT for my son and he then wanted hand cannons. Borrowed some items and design solutions from the reactor, and wanted to make something slim with battery within. Needed: - 3 M3x10 screws and nuts - 6 white 5mm LEDs @ 3V - 1 CR2032 or similar @ 3V - 1 short, thin cable. Mine had diameter of 1mm I think - 1 OFF (ON) switch The + contacts of the LEDs are soldered in a loop around the base, then that fits to the switch, and eventually to the top of the battery through the cable. All the - contacts of the LEDs have contact with the bottom of the battery. With this, all six LEDs connect in parallel to the battery. I didn't by the switch from Amazon, but this looks like the one: https://www.amazon.com/Solder-Free-Momentary-Normally-Terminals-Included/dp/B07DHS2K42 Printed with PrusaMINI+, 0.2mm, 15% infill, PLA. Transparent white with rectilinear infill for the crystal. Aluminium PLA for the ring. Used supports on the plater for the battery holder, and supports for the hollowed-out ring of the crystal, but not for the holes and the arc for the switch. Other than that no supports. Used an elastic strap for the hand, which connects to the cannon using four small holes in the strap and the buttons underneath. https://www.tinkercad.com/things/8jfyBSXOwis
