K40 Cloudray laser head with guides

Remix of https://www.thingiverse.com/thing:5208176 to allow line lasers with a 12mm diameter. Also the mount was to close to the rail so the mount got stuck against it. Made the mount a bit smaller to give it more room.

I love this laser head, I always need to change the focal length depending on the material I'm using. So this saves a lot of time.
I've bought 2 pieces of line laser (9mm and without focus) It shows the point of the laser where the two lines cross. Also it is rather easy to adjust best focus for the laser as well. When the two lines becomes a corner thats your sweet spot. You don't have to adjust it with a gauge or anything. Just put your part, adjust the focal lenght when the lines are just corner. Voila!
