Hephestos Carriage for 4 lm8uu

I have made an upgrade to original
http://www.thingiverse.com/thing:831914
i take NO credit for this one just needed some more features for my own model.

it work for Prusa i3 Hephestos.
and i specially made it for use with Igus lm8uu blushing.

Ok i have a almost final version ready now working and running.
keep in mind this is running a bit tighter then the original carriage but nema 17 and standard step stick can work with it.

i use Igus for min instead og ball lm8uu but you can use what you want same measurments

please Read instructions for get it work.

you need.
-4 lm8uu ball or igus bearings
-9 strips /zip ties
-2 M4 nuts (and a soldering iron)
-2 M4x20
-1 longer screw for the end stop

can be some grinding to get the lm8uu fit perfect and running smoothly on the rods but i try to make the final so perfect as possible with a nicely calibrated printer.
