Sunhokey X-carriage replacement for chinese E3D V5 clone mount by good_idea

=== IDEA ===
Compact X-carriage with following features:
1/ Uses E3D V5 heat sink which comes with chinese Prusa Sunhokey acrylic printer.
2/ Compact, allows to print on 200x200 mm print area.
3/ Uses 40x40 mm fan with nozzle for heat sink cooling.
4/ Uses 50x50 mm centrifugal fan for print cooling.
5/ Uses 18 mm capacitive proximity sensor for auto bed leveling.
6/ Uses LEDs to light the print to see the quality underway.
7/ Uses bearing blocks to avoid play and rods scratches.
8/ Nothing is mounted on the front what allows to observe the printing nozzle.
9/ All parts should be printed without support or bridges.
10/ The heat sink with hotend is lifted up to allow printing up to 200 mm tall prints.
=== FUNNY STUFF ===
I have started this work about 18 months ago. And only close to the end I have occasionally come across this thing http://www.thingiverse.com/thing:1852785
Joshua uses almost identical design but for E3D V6 hotend. The only real difference in idea is that I have lifted up the hotend to win several millimeters of print height. This coincidence very nice illustrates the well known principle of TRIZ: there is a typical path of engineered systems development. Funny!

=== TIPS ON PRINTING ====
If you do not have a print cooling fan the only thing which is not very easy to print is tube for 50*50 mm fan. Put it upright. No supports are needed. Prepare any computer cooling fan, hold it in your hand and direct to print when the very tip of the tube will be printed. Do not hold it too close to the print because the airflow may deform the tip of the tube. If the tip is not very accurate (like it happened in my case) do the following: put hot water in a glass (about 80-90C) and hold the deformated part in water for several seconds. It will become soft. Than you can shape it by hand. Works nice.
