E3D V6 Fan Duct 40 mm (2-part)

thingiverse

This adds a 40mm layer cooling fan to an E3D V6 hot end. This design is a nice touch because it mounts simply using the existing screws in the e3d V6 fan shroud, making it super easy to install. This remix, based on the design by Edsol, is cleverly split into two pieces for added strength and ease of printing with a FDM style printer. Simply glue the 2 parts together with epoxy. Update 6-Feb-2017: STL files are revised to tighten up the tolerances, and now includes a 2-sided version. I've found that the fan duct does an amazing job of cooling the layers; it's a huge improvement over using a desk fan. Here are my print settings: Printer: Folger Tech Kossel 2020 Rev B Rafts: No Supports: No Resolution: 0.2mm Infill: 100% Post-Printing Instructions: 1) Glue part 2 into the slot in part 1 using epoxy, and let it cure fully. 2) Attach a 40mm fan to part 1. 3) Remove the 4 screws that attach the 30mm E3D V6 cooling fan to the cooling shroud. Then position part 2 over the 30mm cooling fan and re-insert the 4 screws. 4) Route the wiring from the new 40mm fan to your printer control board, and test it to make sure the fan runs the right way (e.g. using the manual control in Repetier). 5) When printing with PLA, configure your slicer to turn on the layer cooling fan after the first layer or two.
