New x-carrige for my Prusa I2. No more heat problems. 
Thank you very much, but I am not building. Just replacing some parts on a very well runing Prusa I2 I have build from instructions on http://reprap.com.
Currently I have a printed carrige, but the heat from the nozzle will make it deform over time. Currently its protected by a small isolation layer I have added. But in order to avoid the problem for good, I will replace it with this new one of wood.
Next step will be to make one in Aluminium.
