Laser Case

This is technically a remix from a ecig mod case but not much other than the basic shape is original it is heavily modified to be used as a laser holder. I wanted to make some DIY lasers portable just for fun, I had purchased some different size and color lasers so there is 3 sizes 10mm, 12mm, and 14mm tops, I used standard 18650 batteries with a micro USB charger Part # TP4056 and Pololu Adjustable Step-Up/Step-Down Voltage Regulator S7V8A that I was able to fit right on the back of the laser driver both from amazon. The voltage regulators are great because they will keep the voltage constant no matter what the input and depending on the laser they run at different voltages, and the TP4056 charger has low voltage protection. I used epoxy for the switch and hot glue for the rest including the top everything is a pretty tight fit so you might have to sand a few parts to get them to fit. This should go with out saying but playing with lasers can be dangerous please be careful I have found some lasers that can be really powerful for pretty cheap so have fun but at your own risk.
