This is a Remix of the Printrbot hotend cooling fan for the all metal Ubis hotend.
I was trying to make my printer quieter, so I wanted to get rid of the rattling that the original did against the hotend, as it was just a snap on fit and got looser and looser over time.
This is a remix of the official Printrbot hotend fan mount.
Since I switched to the 50x15 blower, I was able to mount this to the frame to kill the rattle. I originally tried to make it not actually snap onto the hotend, and not touch it at all, but I ended up abandoning that as it always seemed to shift and rattle anyway, plus it was blowing down onto the part, which was not what I wanted. Maybe someday I will give it another go.
I also changed to a 40mm fan instead of the 30mm fan, which greatly reduced the noise level (since I can run the 40mm way slower than max and still get plenty of cooling.
