Ball Socket Fan Mount for MakerGear Prusa.
Description
Instructions
Note, the ball socket I created has a slightly bigger diameter sphere to it than StefanHH's original ball socket. I found the bigger diameter added more grip to keep the chain in place.
The fan attaches with an M3 bolt.
If you don't want the fan attached to the X carriage, you can attach it to the threaded rods using the included 3rd mount. It connect in the same way as a Prusa endstop mount.
I recommend Printing in ABS, as PLA will loosen up over time (I think because of the heat emanating from the build surface).

After I printed 3 ball sockets, I decided to put them together before I printed more, When I did this they broke. They looked absolutely fine until I connected them. They were printed in PLA. Im thinking PLA may be too brittle for these. Next time I'll use ABS. Too bad too. I really wanted one of these.
Strange. I've made them in both PLA and ABS, the PLA ones I have never seen break. Perhaps you are experiencing the shells bug(skeinforge)? Try turning all three extra shells options to 0. Shells bug causes thin walled areas to not be filled in and the only way to fix it is to disable the shells. However, once you are done with the print, make sure you turn them back on, as extra shells are critical for added strength (in objects that aren't experiencing the bugs).

Actually really hard to print
Ya, kinda. Requires a nicely tuned printer and maybe some adjustment to infill. Not very effective either, over time they don't hold the shape you set them in. I wouldn't print it again. It was cool for a while.
