Super cool X carriage 9003!!!

This is another X carriage I designed. This one attempts to reduce the size and complexity of my previous design. It has all the features of the previous version, but is much easier to print and use. It should also be easier to work on.

- IR probe mount
- adjustable x-min trigger
- integrated air duct for part cooling
- adjustable belt tensioner
- still "over 9000!"

NOTE: This design has been superseded by the 9004.
