The file 'E3D Chimera And Cyclops X-Carriage / Improved Stability For Prusa I3 3D Printer Model' is (stl) file type, size is 71.9KB.
This is a remix of http://www.thingiverse.com/thing:833722 for use with LM8LUU (long) bearings (4.5cm long vs 2.4cm long) for much improved stability. And also a much better and sturdier holder for the driving belt.
Use the mount part from the original design with this carriage (not included here).
4 Holes allow you to access the screws to un/secure the hotend from behind like in the original design.

Some notes:
This carriage is much lower than traditional prusa i3 carriages, on some printer (on mine for example) the x carriage couldn't go down enough without cut slightly in the frame to avoid it hitting the coupling to the Z axis drive screw. Took only a couple of minutes with my dremel and a tungsten carbide burr.
Works like a charm so fast and I got a total of ~150g for the whole thing including 2 print heads. My previous dual extruder mount was about 3x heavier including print heads.. I do notice an improvement in quality.
