simple XY carriage for a custom H-Bot

This is a simple XY carriage for a custom H-Bot my friend was building. (I just designed some printed parts for him).

>>> This optimizes the print height to the maximum (as can be done from the XY carriage perspective)
>>> The Fan duct is removable.

Uses:
E3d V6 hotend
LM8UU bearings
8mm smooth rods
30mm fan

Use an M3 screw and nut to terminate the GT2 belt.
