I sold my CR-10S, so I will not be doing any more development / revisions to these file.
Remix of https://www.thingiverse.com/thing:2562314
I printed the original design at 0.2mm layer and during install the mounting tabs cracked. After a few prints i liked the offset nozzle design to blow part cooling air right where it was needed as compared to a couple other popular designs. So in hopes of making it better: I reduced the hole diameter by 0.4mm on diameter ( its just snug on the threads now), I also added 0.5mm to each end of the mounting hole tabs and finally I stretched the small bevel over the whole width of the fan shroud so it was less likely to catch the print if it was going to lift.
No Raft required.
No Supports required.
Prints good at 0.2mm layers.
cr-10_oem_fan_nozzle_offset_stonger.stl is the original file. Use Version 2.
cr-10_oem_fan_nozzle_offset_stonger_v2.stl added 1-19-2018
Added a even more material around the mounting tabs.
Recontoured surfaces to removed weight and sharp edges.
Greatly reduced file size.
Added more Remix reference files to link parts together.
