These are my new thick sheet parts for RepRap Mendel. I was inspired by the mounting plate for the TechZone boards (http://www.thingiverse.com/thing:2174). I used a modified version of this for my mother board and extruder. And then made a board for my steppers. I have also included my modified froglet that is simpler for cutting out with saws.Be sure to check out pictures and more information about my Mendel @ reprapbreeding.blogspot.com/Cut out per full sized PDFs and attach to Mendel. You only use the y-bar-clamps and circuit-board-spacers (you will need 4 of each). You do not use the "circuit-board-bracket-m3_4off.stl" with this design. I also just cut my build plate square (eliminating the nozzle clearing area).
