40mm fan duct mount with X-axis belt tensioners

A modification of the standard fan mount from the Ultibots 40mm Fan Duct. This mount adds tensioners on both sides for the X-axis belt. Uses 2x M3x10mm bolt and 2x M3 nut.

Nut goes in underneath, bolt goes in from outside, belt goes under the mount and around the small curved pieces, then can be zip-tied to itself. Repeat for the other side. Tighten bolts to increase tension.
