*1 Bracket Set. I had these made by the developer's machinist, who cuts them from Lexan. This is the one step that's not really open source, as the machinist won't release his drawings. You can contact the developer through his Sourceforge project, listed below. Cost was about $230 including shipping. PS:One Members, I made my own drawings from the machinists parts, and I think these could be made on one of our 3D printers or CNC machines. Contact me if you want them.
