Yet Another Wanhao i3 Fan Shroud/Cooler

thingiverse

So like most people, I've been rocking the DiiCooler for a long time on my Wanhao i3. It's a great cooler, but it's time to try something new. Mainly because I've used my current DiiCooler for so long that it had a few burn holes in it... At first, I tried designing my own circular cooler similar to the DiiCooler, but I gave up on that project eventually because it got overly complicated. At least I got a few working prototypes of that design! Now starting over, my main goals were: hot end visibility, minimal hot end temperature fluctuation, and performance similar to the stock cooler on the Ender 3. It's currently my favorite printer, so I set out to design a cooler that could at least be simple and also perform halfway decent. If you're looking for a high-performance cooler, this probably isn't it. However, I think it performs well, and I've posted pictures of the 50mm bridge test performed by both the Ender 3 and my new cooler on the Wanhao i3. I designed the fan shroud to blow air at an angle under the nozzle. This design uses a 40mm fan (I based the holes from the fan shroud on cablestud's thing:2789648). Holes can either be tapped or gently forced using a M3 bolt. My final fan shroud was printed in PETG, and I forced a couple of nuts underneath the top connection just to be safe. P.S. I also uploaded my current 40mm fan covers. Their design is one I made a long time ago from a combination of several fan covers here on Thingiverse. If I can remember the exact designers, I'll give credit where it's due! They are pressure fit with posts to help hold them in place.
