Ender 3 40mm Fan Adapter for Hero Me Duct

thingiverse

I've been working on this project, but I had to pause it when my house was flooded and my workspace got damaged. Once I get back on track, I'll revisit this and fix the one flaw that's keeping me from finishing it. This modification adapts a 40 mm radial fan to fit into the blower fan opening of the Hero Me V6 Fan Duct. It works perfectly as is, but there's a small issue with the inside of the hole where it attaches to the top of the Hero Me unit. Don't worry, though - this won't affect performance or the attachment because you don't actually need that top hole. Also worth noting: if you do choose to use the top hole, you'll need to grind down the screw head so it's smaller in diameter. If you don't, your fan might not sit flush properly.
