The file 'CobbleBot X Axis Belt Block 3D Printer Model' is (skp,stl) file type, size is 393.8KB.
A block to attach the X axis belt to rather than the silly screw that comes with the printer. I used that same silly screw to hold down this block. I also had to use a few washers to get the height adjusted properly.
Update:
Check out this remix: http://www.thingiverse.com/thing:1072943 Its much better.
