Description

This thing is for mounting a focus lens directly to a Reci W6 laser tube. I think it should work as is on any Reci tube, but it parameterized, so it can easily be adapted for other tubes.

Why would you want to mount the lens directly to the tube? I suppose for most setups it would only be used for testing the laser. For my purposes, I plan on moving the whole laser tube on my large CNC machine, so I should be able to put this to good use (I am not going to steer the beam, I am going to steer the whole tube).

Works great. Very snug fit on both the laser and the laser head. Video of it in action here (it is the green part):

The laser head I am using is this one: lightobject.com/1820mm-Laser-head-w-air-assisted-Ideal-for-K40-machine-P701.aspx

Special thanks to TrevM for making the really useful thread library!

Instructions

Printed at 101% (for PLA shrinkage), use slic3r (0.1 layers, 100% fill) and fits the laser tube and laser head perfectly.

A chunk of plastic connected directly to the output of an 150 watt laser does not seem like a good idea to me. It will heat up - quite a bit.

I think hot plastic mere millimeters away from the output window is going to mess it up.

It is critical that the output window be kept clean. Anytime you have to clean it you risk scratching it and drastically affecting the laser's efficiency You can't replace the output window, once it is damage
d, the whole tube must be replaced.

Well the Laser head I purchased (the black part and the end of the laser) is plastic.

It also has air running through it (air assit) that should keep things cool. That is what the tube hanging down is - and that helps keep the window free of contamanation.
