Longer LK5 Pro Satsana Style Fan Duct 40x20 & 5015 Fan

thingiverse

This is a Fan Duct for the Longer LK5 Pro 3D Printer designed for a Micro Swiss hot-end I had purchased. I had originally chose to modify a Satsana Remix so that the mounting aligned with the mounting plate and fit the new hot-end, but after a bunch of trial and error, I decided to remake it from the ground up. I was also able to modify and enhance the air path through the part for better flow as well. The mounting locations for the stock LK5 Pro fan left a lot to be desired, and on initial prototypes, the right side of the duct would sag ever so slightly. I wasn't a fan of that, so I added a secondary bracket to the upper right hand side that would snug it up against the top edge of the mounting plate. This is adjustable, and eliminates any sag from that side. I used a M3 knurled brass insert (M3x4.6x5.7mm from Amazon) set into the main duct, that allows the retention bracket piece to screw into to add that support. All fan mounting screws are M3. The 40mm from fan location will work with either a 40x40x10, or a 40x40x20 fan. A standard 5015 fan on the right side will work just fine with M3x20 screws. All screw holes are self tapping, apart from the hole with the insert.
