3D-Printed Parts Let You Assemble Your Own Biggest Fan

It is acquiring near to the time of 12 months when we need to have to start carefully vetting assignments listed here at Hackaday. Right after all, no one likes to get punked by an early April Fool’s joke. But as silly as this outsized Laptop fan seems, it absolutely sure appears like a legit build, if a little bit on the pointless facet.

Then once again, perhaps pointless is way too harsh a word to use. This 500-mm admirer is by [Angus] more than at Maker’s Muse, and it represents a ton of design and style work to make it buildable, as perfectly as workable and (largely) safe and sound. Making use of each CNC-reduce MDF and printed pieces, the enthusiast is an embiggened reproduction of a normal-sized scenario admirer. The fan’s frame had to be printed in four parts, which lock collectively with clever interlocking joints. Each of the 9 blades locks into a central hub with sturdy-searching dovetails.

And strong is essential, as the supporter is run by a 1,500 Watt brushless DC motor. With a 4:1 reduction thanks to a printed equipment train, the fan spins at all around 3,300 RPM, which will make a terrifying sound. There is a minimal bit of “speed-wobble” evident, but [Angus] managed to endure testing. The admirer, nonetheless, did not — the 3D-printed gears self-destructed just after a full-pace examination, but not in advance of the enthusiast did its greatest wind tunnel imitation. And the RGB LEDs seemed terrific.

This a person reminds up of some thing we may well see [Ivan Miranda] occur up with. In fact, his super-sized 3D printer may possibly have been just the issue to shorten [Angus]’ print periods.
