This is a redsign of a 50Watt laser tube holder for the 40 Watt K40 eBay Chinese CO2 Laser version. If you decide to do this be forwarned it is at your own risk as the laser tube operates at high voltages and can deadly if you do not know what your doing! Also be sure to visit our new Open-SCAD site and channel at http://OpenSCAD.DIY3DTech.com
Note: this may not fit all k40 laser types so double check before tearing yours apart. Also as you see the fit is "tight" so use care when assembling.
We have also created a video series on this project too and episodes can be seen on YouTube by going to https://youtu.be/RgE0VAuYzoE for episode one and https://youtu.be/SkjaRbDl4HI for episode two. The final episode (#3) can be watched at https://youtu.be/bddpgmj9Vu4 to see how everything comes into alignment.
