Flsun qq qq-s 5015 turbo cooling mod

thingiverse

this is a mount for two 5015 blowers to get rid of those 4010 stock blowers. the stock fans are fine if you are printing medium/slow. These blow 10 times the air and I'm not joking. I'm going to publish a couple of cooling nozzles for these, the stock ones point too far from the print, the most used alternative ones have a very constricted air flow. I did a lot of scientific testing by printing small things in vase mode very fast, and overhangs. how to use: print the adapters. the hole at the top is 4mm, you need an M4 bolt each and a threaded insert or a nut. the bolt needs to be 25mm or more if you use threaded insert, 30mm if you use a nut. fix the blower to the adapter, remove the stock fans and bolt these on. of course you will need to solder the new blowers on. there are many blowers out there, the best cheap ones are marked "Pengda". of course you need 24v blowers since the printer is 24v. AVOID WINSINN blowers!
