OpenForge 2.0 Tudor External Walls (Cross Beams) (Revised)

This is the cross beam set of tudor external wall tiles. Unlike the internal tiles (which I'll update), I made sure here that every tile size from 1x1 to 4x4 has a cross beam version. See the basic set for an explanation as to why I revised these.

The other sets are here:

* [Basic](http://www.thingiverse.com/thing:1799652)
* [Set 1](http://www.thingiverse.com/thing:1799678): Diagonals based on the basic set.
* [Cross Beams](http://www.thingiverse.com/thing:1799695) (This set)
* [Set 2]
