This is a set of parts that allow you to hold a fan aimed at your bed that you can easily flick on or off to get out of the way in order to cool your prints and still have easy access to your build area. I was inspired to make this by mrice's 80mm fan mount (http://www.thingiverse.com/thing:91003), but my mount broke easily and I didn't like how the bar clamp would wear down after moving the fan in and out of the way and would constantly need tightening. This solution uses much more plastic, but it is much sturdier and easier to flip the fan out of the way thanks to the hinge. I also used openscad so it is all parameterizable. You can print out a bar as long or as short as you want and I also have a model for the fan mount that works on any sized fan (I included STLs for 70mm fan and 80mm fan. I may add a nut trap on the fan mount and a hole for the fan wires to pass through on the arm in a later version.

Requires:

• 9 M3 nuts
• 7 20mm M3 bolts (for the fan, mount and arm)
• 1 40mm M3 bolt (for the hinge)

Mount Assembly:

• print out two copies of the hinge clamp. Insert a trapped nut in to the hinge hole on each. Place one upside down and on top of the other - they should click in. Place the hole of the hinge in the arm inbetween the two hinge holes in each clamp and screw the 40mm bolt in through the entire hinge. Screw on another nut on top of the top hinge to hold the bolt in place.
• Next clip the mount onto the 8mm threaded rod where you'd like to mount it. Screw and tighten 2 m3 bolts (note the nut traps are on opposite sides for each piece).

Fan installation

• Screw 4 m3 nuts and bolts through the holes in the the fan onto the four holes in the mounting plate
• screw a nut and bolt in place to mount the fan mount onto the arm.

Enjoy!
