40mm FT5 Fan Shroud - Slimline Stepper, Titan Aero V6, 713 Maker (Ultralight)

thingiverse

EDIT 2/16/2019: The first prototype performed impressively well, and now I'm using a second version. It features sturdier screw mounts, and the cutouts for heater wires have been relocated and enlarged. Fusion archive and .STEP files are available for your convenience. EDIT 2/23/2019: Minor adjustments were made to ensure wire cutouts no longer clip through the body. The back side was moved further away from the heat block to prevent melting. This is the final revision, enjoy! BOM - 3 M3 x 25 screws - 4 M3 x 15/25 screws (dependent on fan depth) - 1 Axial case fan, 40x40x10, or 40x40x20 I seem to have encountered a common problem: Upgrading to a cool new extruder, assembling it, realizing none of your cooling fan ducts fit. Printing more out and finding that those don't fit either. Proceed with tears or anger as necessary. Joking aside, when I upgraded to an e3d Titan Aero setup with 713Maker Ultralight carriage, I discovered all the fan mounts seemed intended for the stock stepper motor, rather than the e3d Slimline motor. My attempts at remixing another duct failed miserably, so I present to you my own. This cooling fan duct is designed to be easy to print and easy to install. Print in the default orientation. Supports shouldn't be necessary, but may be helpful for the hot side openings. Use "Supports on Buildplate Only" in this case. Channels on the inside will help with bridging on the top of the duct. This duct features a generous clearance with the heatblock to prevent melting, and provides notches for the heater cartridge/thermistor cables. The design has been finalized, source files and STL have been included for your convenience.
