Creativity ELF Dragon Hotend Mount

A while ago I posted a NF-Crazy mount for my ELF. It worked really well but it turns out the NF-Crazy wasn't as good as I hoped in terms of flow rate. So... Since I has a spare Dragon HF, a spare Orbiter and a desire to learn FreeCAD's Assembly 4 workbench, I came up with this contraption. It's a new from scratch design based on a similar concept to of my NF-Crazy mount. Main goal was better cooling without loosing XY print space due to collisions with the steppers or top plate.

The fan ducts are a big improvement over the previous design since a) they are less restricted that the previous design and b) are internally re-enforced to prevent sagging when printing ABS with fans off. I print the fan duct in two parts (the fan attachment and the duct) and use Tamiya Cement to glue them. Everything expect a small portion of the fan attachment is meant to be printer withou
