K40 Laser Engraver Mirror Alignment Plug

thingiverse

Here's a simple holder for a mini 6mm laser diode module that fits snugly into the tube of a K40/equivalent CO2 laser engraver/cutter. There are channels on the side where the laser module wires can exit the tube and connect directly to a battery. A flange is included to prevent the plug from going too far into the tube, ensuring it lies flush against the tube for precise laser alignment. This is my first project, so please let me know if I'm doing something wrong or ignorant. Don't hesitate to educate or correct me - I'm here to learn and improve!
