BIQU H2 Fan Duct for 5015 Parts Cooling Fan

thingiverse

This is yet another parts cooling fan duct for a 5015 radial fan to mount to a BIQU H2 direct drive extruder. I'm calling it a remix of [looxonline's](https://www.thingiverse.com/looxonline) fan duct, although I didn't directly modify the original stl. This was modeled from scratch using measurements taken from one of his that I printed out. I also referenced the drawing included in the H2 manual, keeping most of the fitment from the original design, which was already excellent. This design has less angle to the fan while still allowing easy manipulation of the manual feed gear, with completely redesigned air channels. I mainly wanted to change the flat bottom, which I found made it difficult to view the nozzle and surrounding print area while a print was going. It will print without supports or rafts, although the surface area on the build plate is a kinda low so you may need a raft or brim if it's not adhering well to your build surface.
