Prusa I3 E3D Titan Aero carriage with 18mm probe mount and part fan

This is an X-carriage for any prusa-ish printer which uses an x with 8mm rods situated 45mm apart from each other (center to center), an 18mm ABL sensor and a 5cm radial part-cooling fan.

The carriage I print with 30% infill and no support. 4 top/bottom solid layers and 4 perimeters. The fanplate, same, but with support from build plate.

The carriage uses bolts for tensioning the belt against, this is stronger than printed plastic. Also it allows to use rings to lock the belt in place. Las
