Wanhao Duplicator Hi Capacity Fan Bracket

thingiverse

I'm glad I came across this pair of laser-cut parts - a spacer and bracket designed specifically to accommodate a Hi Flow fan on my trusty Wanhao Duplicator. The fan duct (check out this fantastic design: http://www.thingiverse.com/make:117375) requires a standard 40mm fan, which is exactly the case with my new fan GUB0412VHF, measuring 40 x 50mm in size - now all I needed was an adapter! It looks like some M3 tapping and countersinking will be necessary to complete this project. The spacer measures 6mm in thickness while the bracket clocks in at 3mm thick. The result has been a marked improvement in performance, with a distinct "wind chill" noticeable when the fan is running its course - a bonus! The fan employs two counter-rotating impellers, which helps to minimize noise levels. Although I initially worried it might be noisy, this concern proved unwarranted. For now, the fan has been temporarily relocated to allow for safe printing, secured in place with QD hinge pins. After all, I don't want it colliding with my printer's door while printing is in progress - a safety precaution worth taking! But during commissioning trials, caution is indeed warranted. As expected, print quality has taken a notable leap forward, and those overhangs that previously plagued me no longer pose an issue. What's more, I discovered that each motor operates at 12v; to bridge the power difference between the Wanhao's 24v output, I'll just need to wire them in series - a clever fix!
