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.
openscad files are in the ZIP archive. (The easiest way to include multiple required files.)
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.
