5015 fan emulator

thingiverse

I have been fighting bad 5015 fans for a couple days... I wanted to get rid of the big clunky dual 50x50x10 (2 12v fans run in series) parts cooler (I think it's called a batfang) on my ender 3.... so I printed one of the nifty hero me fan units that all of the cool kids have and I've tried 4!!! different 5015 fans on the dang thing and they all died in less than a day... these 12v fans running in series (the ender3 is 24v) have been working like beasts for months... I checked the voltage... I am at 24.5v at max speed on the fan at the circuit board... I could adjust the PS down a half volt, but that shouldn't matter since I am not even running the fans at full voltage... mostly it's set to around 19v (80% speed) at most... so I got pissed off... I am not quitting on finding one of these holy grail 5015s that can actually work... but while these 4 go back to die in amazon hell, I whipped out my trusty fusion 360 and cludged the crap out of a 5015 emulator using the 50x50x10s stacked... because they are still 12v... I realize this probably won't get any makes... but it is 3 parts printed as flat as you can... (I had to print with no parts cooling remember? I took off my batfang and didn't want to solder it back in) and I connected the parts with CA glue and kicker. then I hacked up my hero me so it would fit a bit better... I am going to print another one as soon as I find real 5015s... so for your amusement, or if you want to play at home.... you need 4 m3x20 screws, (or m3x10 if you have a 24v 50mmx10 axial fan) some fans and a bit of bile...
