UM2 Fan Duct unsupported

My own version of the cooling fan duct on the Ulitmaker 2. Minimalist design, does not interfere with plate clamps as much as other versions and still clears the bars. Requires only one of the screws the UM2 came with for the ducts.

This design does not require any support structures at all to build, which was a goal of mine when I designed this. Lots of sexy curves. I printed mine in white (it was what was in the machine at the time), but I think black would look better.

WHEN PRINTING, make sure that you orient the ducts as if they were mounted. Any other orientation won't let you print without support material.
