This is my first attempt to build a laser etching head that i can attach to my 3D printer..and laser etch things with it.
The idea is to use the low power laser modules that I bought vial amazon ( 10 for 2.50Eur) - thus 25 cents each, to combine these together into a focused beam which will be powerful enough to burn things.
Each module is rated at 35mWatts so with 10 I get 350mW at the point where they all converge.
I chose a focal length of 5cm (50mm) and created the holder for all ten la
