Fan Mount (RigidBot)

Mount for attaching a cooling fan to the RigidBot extruder and a couple of optional fan nozzles. The fan clips into a hinge and can be tilted up for easier nozzle access. I made the extra nozzles to experiment with.

I used the following [24v fan at Amazon](https://www.amazon.com/Connector-Brushless-0-15A-Blower-Cooling/dp/B00H8VV0XK/ref=as_li_ss_tl?ie=UTF8&linkCode=sl1&tag=whirligh-20&linkId=452f8aec6d0f60359aa043cd3eeade3d) (the wire polarity needs to be switched so check that before plugging it in). It seems to be a common part and can probably be found at other places for less.

For the upper right fan hole, I used a 6-32 flathead machine screw, but other options will work as it threads into the plastic.

I use a 1/8" build plate so the fan is designed to clear the clips. If you're not using a build plate, the fan probably may not clear the bed leveling screws (I haven't tried that configuration).
