Hey, everyone! This is my first upload to Thingiverse, and actually my first 3D design. This is my custom laser gun, designed to work with the laser module and button from my Colemeter Mini Laser Engraver (or any clone). This particular gun has a 1000mW laser, and is as simple as the laser module, button, and some AA batteries. That's it! At the moment it has only 4 AA batteries in it (which is still powerful enough to burn paper or plastic), but you could add up to 5 or 6 AA batteries in series to make it even more powerful. The design will need to be slightly modified depending on the laser and button you choose to use, but that's as simple as just increasing or decreasing the diameters of the two holes. So far it works great, but make sure you wear protective glasses (to shield your eyes from the light), and don't point it at anyone obviously!
