CR-10 extruder and part cooling fan mount

thingiverse

This replaces all or part of the existing extruder and part cooling fan mounts on at least the CR-10S models. Hopefully somebody can confirm if they works for other CR-10 models. The design allows you to see the extruder nozzle while printing. The part cooling fan mount/duct has small slots to allow for adjusting the height off bed, granted they are small but at least allows for you to adjust it to your liking. I designed them so you can start off with both part edges flush with each other then adjust. I dropped mine down lower by 1mm approx. Due to my extruder and part cooling fans were wired incorrectly, I came up with this solution to use a spare 40x40 fan, that and I don't much care for the blower type part cooling fans that came with the CR-10's. With this setup I was finally able to produce the best looking benchy print I've ever done. Benchy's hull is smooth as can be. To assemble, besides removing the existing steel extruder housing and fans, remove the two screws holding the extruder to the backing plate. You'll need to loosely assemble the extruder into the new housing, slide the tab on the right side down over the backing plate and align as best as possible then loosely attach all four screws, the two to the backing plate and the two holding the extruder to the backing plate (in what ever order you can, just loosely). Make sure the extruder is where it needs to be then tighten it down first, then tighten the two screws holding the mounts to the backing plate. The main two files that make up the design in the pictures are; 5015-fang-mod1_extruder and part fan mount.stl (base remixed from spider65's "Dualfang" design) CR-10 part cooling duct.stl Supports are required for those two files due to the preferred orientation for printing however none of the internal ducts surfaces require any. EDIT, fixed the orientation of two files. Added a couple more fusion files also. You'll need (3) 3mm x 8mm long Flat Head screws to connect these two parts together. As well as you'll need 3mm x whateverlength you need to mount the fans with. You'll also need (1) 40x40 radial type fan as the stock part cooling fan will not work with any of these parts. The two other files are extras if anybody are interested but both have been designed for CR-10's and were used before this final design. They are; 40x40 part cooling duct with 13.8 degree angle.stl (just the duct) CR-10 part cooling fan mount and duct_for stock setup.stl (if you want to keep the steel extruder housing cover, you can replace the part cooling fan with this) I've included four F360 files. Can't say the F360 files are the best in the world but they work for me. In the 40x40 fan hood.f3d file, I used a construction workplane to define the outlet angle. (Set the angle to 0 degrees and this part will work for many printers other than CR-10's) HTH someone out there!
