CR-6 SE 40mm Part Cooling Fan With Additional Vent

thingiverse

I decided to try to improve the already brilliant part-cooling of onlyDave's system and added in a third outlet pointed at the part from the direction of the fan. This is deliberately smaller than the other two as it's directly in the direction of the air-flow. I've made two options and I printed the one with the smaller output. You can see how the dimensions compare in the attached images. I also added some fillets to the corners. Obviously this is going to be close to the hotend - so print in PETG or better. I think my printer may be slightly over-extruding and I found it best to run the m3 screws through the holes first to cut the threads better before trying to mount it all on the bracket. This is just the duct, you can print onlyDave's original fan mounting bracket if you're using a 4010 fan or mine here https://www.thingiverse.com/thing:5406079 if you're using a 4020 fan. See my make for more and better photos as Thingiverse annoyingly limits you to 500k for images for things but not makes!
