40mm Fan Bracket for Jonas Kuehling's RepRap X-carriage by CarlCravens Dec 15, 2012

Description

This is a bracket to attach a 40mm fan to Jonas' Reinforced Prusa X Carriage with Slim LM8UU Holder ( 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.

 This, for one.  http://www.thingiverse.com/thi...

It's still a side-mount, though.  I've seen rear-mount somewhere before.

which did you find? I've been looking for one as well. Mainly, one off off the back part by the belt holder.

Ya know, I looked for fan mounts that fit this carriage more than once... why do I find them *after* I made my own?

Instructions

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.
