Design revision 3: pics and stencil

This design is based on my updated hardware selection stated in the previous update. As before these images are more or less to scale and the measurements are correct. But as before since I haven’t actually bought anything yet I don’t know how much the design will be changed when wires are added. This update also includes the changes I’ve made regarding optics (see post on not understanding optics). Please use the stencil once I've uploaded it instead of this image.
