About this 3D model

Just playing around with the idea being developed by markab and alex1984. I beefed up the gussets holding the 10 mm Y axis threaded rods and moved some holes around to reduce the volume of plastic needed. Be prepared to drill your own holes to bolt this one in place! BTW, the version ending with 6_6 is for 6.6 mm thick aluminium plate, known as 1/4 inch here in Canada.
