Nerf Kronos Light and Adjustable Laser

thingiverse

Thing is made out of a Dollar Tree laser and flashlight. Both need to be disassembled and soldered to make it work. The battery is the three triple A holder from the flashlight, with wires soldered onto the contacts. It doesn't hold to the gun super well with friction. Epoxy or double-sided tape should really help. I used a single-side sticky foam and that worked, but might not hold up for the long haul. Switches were sacrificed from some cheap speakers, but any with the right dimensions will do. Print files in any way that makes sense to you and how you like to print. Strength shouldn't be an issue except where the nuts are held in place; don't over-tighten them.
