I finally got around to making the mounting brackets for attaching the elements to the base. I'm quite pleased with how well it printed, considering that our printer is very inaccurate.  I will hopefully post the skp file up shortly. The bracket is designed for a 3/4 inch square beam and made to hold a 8 mm piece of round stock. You would attach the element to it using a pop rivet or elastic band. the problems with it right now are that it is uninsulated, so i will have to put some sort of foam or rubber in between the rivets and the element, and that I'm not sure about the strength of the pla.
