I just love the design and the laser pointer idea, and I adapted it to integrate two other great ideas: 1)from http://www.thingiverse.com/thing:445354 (combining two lines laser pointer to have a cross working on all heights) and 2) https://www.youtube.com/watch?v=CC9kGOlxlHs (adjusting focus, ihooooo, thanks bro!)

A thirs part can be found here: https://www.youmagine.com/designs/k40-chinese-lasercutter-air-assist-with-cross-lines-laser . I wanted you to have a look at his page to see how it works and to give him the credits. I was not planning to use it but I might be wrong! About the BOM, I bought these cheap lasers here, I guess they are ok because I'm always optimistic, but to be honest, I did not even check the size :-) http://www.aliexpress.com/item/Free-Shipping-Red-5mW-650nm-Line-Laser-Module-Focus-Adjustable-Laser-Head-5V-Industrial-Grad/32290741097.html
