KC-135

Removed many of the details that made this design un-printable. Improved the durability of the tail boom and tail for printing. Increased the size of the print 125% to produce walls that are strong enough. The wings will needed to be printed in the vertical direction with full supports. They will be tricky to remove - but should break off cleanly.

Be sure to add a few extra walls on the wing - they tend of be weak and crack as you try to remove the supports.
