Pylons for 40 Watt eBay Chinese Made Laser Cutter

Printed these pylons for my K40/ 40 Watt eBay Chinese Made Laser Cutter to place 1/8″ piece of material at the proper focal height to cut and engrave it.  For me with my bed mod (see video here: youtu.be/ixx-YyAJhfs) it worked to be 1 inch with the light objects air assist head.

Aiming Gimbal for K40 / Chinese eBay 40 Watt CO2 Laser Cutter & and Engraver

To help with the positioning of the laser cutting head we modified this design from Thingiverse and added a couple ball configuration (one for 9mm Laser another for 3mm unit).  Please keep in mind that the point will vary with the parallax to the top of the object so it mean to only be a general means of aiming, yet very simple and effective.  In the example, we used a very small 3mm self contained laser diode & driver press fit into the sphere and some heat shrink tubing on the back side for extra support.
