K40 Aiming laser add on.

Here is an add-on for aiming lasers for the popular K40 laser cutter. It uses 2 line lasers (https://www.amazon.com/gp/product/B012V3U3KK/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1). I am using 1/2 " cpvc pipe from Lowes to hold the lasers. The CPVC pipe is glued into the add-on to hold each laser. Two set screws are used on each holder to keep the lens from turning and to keep the laser from falling out.
