About this 3D model

I\'m in the process of building a MakerScanner, but ran into the problem that the laser line proyector I have is quite big and I didn\'t wan\'t to take it appart. Also didn\'t want to buy another one as they are expensive at the hardware store and I wanted to see if I could make one as cheap as possible by modifying a cheap red laser pointer from the dollar store. It turns out it was really easy to do and only needed a laser pointer and a small piece of a plastic fresnel lens.
