co2 laser head

I am mirroring the content, not originating it. I'll likely add more pieces for 20mm mirrors later. It appears you need a place to pump air into it. This design is based on a CO2 laser head mount from https://www.youmagine.com/designs/co2-laser-head-mount. It's intended to be used with the 30mm mirrors cut from hard disk platters. If you prefer real mirrors, you can use those too. Just keep in mind that the optimal distance from the mirror to the mount block should be about 2mm. This design has been tested on a 100 Watt CO2 Reci Laser tube without major issues, after aligning the laser properly. Your results may vary. I recommend using this for 40 Watt CO2 laser tubes or lower, as the mirrors tend to get very hot on larger lasers. Adding a heat sink behind them might help. I'll post images taken with a FLIR to see if the mirrors deform during lasing. All hardware in this design is 3mm thick. The three shoulder screws are meant to hold an elastic band or o-ring as the spring for adjusting the mirror angle. Thumb screws are 12mm long; regular screws can be used instead. The nozzle tube v3 has a slight taper on its end for easy slipping on, and the neck area around the lens has been strengthened.
