Laser Pointer Holder for 40W CO2 Laser

I recently acquire a cheap chinese 40W CO2 laser engraver/cutter. It's great value for its price but not user friendly. The machine do come with red dot laser side mount next to laser head. It's simple but never line up correctly to the actual CO2 laser light path.

In the high end laser machine, it use ZnSe or GaAs lens as beam combiner. However, the cost of lens just way too expensive for this low-end machine. So I found [39188] have a great idea to make a lever to drop the red dot laser on the light path when the door is opened. And once the door is closed, the red dot laser will put aside to allow actual CO2 laser to pass through. The addition feature for this design is this also works like "Laser Beam Guard", when the lid is open, it will block the CO2 laser in case the laser misfired.



Thus, I start to design my own lever holder and pivot holder for the chinese laser machine.

I made the pivot holder be a "clip on" device so you can snap on the machine with out modify
