40mm Fan Bracket for Jonas Kuehling's RepRap X-carriage
by CarlCravens, published
This is a bracket to attach a 40mm fan to Jonas' Reinforced Prusa X Carriage with Slim LM8UU Holder ( http://www.thingiverse.com/thing:18657 ), which has a stub on either end to attach accessories.
I built my printer two weeks ago, and this is the first thing of my own design I printed on it. I probably made a stupid mistake... just let me know.
Technically, it's mostly parametric. If you plug in dimensions for a larger fan, it should all scale... but it won't fit between the axis rails. But you could easily adapt it to something else.

I printed at 30% infill. It's pretty trivial... bolt the fan to it, bolt it to the carriage, plug the fan into your controller.
12/18/2012: Be sure to aim the fan so it doesn't blow on the nozzle. I had problems with the nozzle dropping 10C and "prevented cold extrude" errors when the fan kicked on. I'm working on a better ducted version that will only hit the part.
