Quick swap E3D mount and Fan Duct for Ender 3

thingiverse

I designed this to provide easy access to the bowden tube fitting, making it a straightforward fit to the Ender 2 and 3 as well as other Creality builds. I've tested both versions - a simple block to hold the E3D V6 heat sink on a stock Creality printer and a second iteration with a hinge. Both types work seamlessly with the fan mount and duct mentioned below. The fan duct has been reworked from this clever design: https://www.thingiverse.com/thing:839620 (Many thanks to eipionezero for including the Solidworks file). Initially, I found the original fan duct to be quite thin and using PLA at the time had a tendency to sag slightly. I was worried it might pop off when unattended, so I beefed it up and added an swivel screen to turn off part cooling. I liked my design but apart from the screen rattling occasionally, the whole assembly blocked my view of the nozzle. To resolve this, I made a cutout, which didn't work with the swivel screen, so I opted for its removal. It still looked like it might fall off, so I created a magnet mount with an index. The magnets were less than reassuring, prompting me to print a custom flexible strap from TPU and call the job done. Currently, I'm working on perfecting a direct drive mount for this setup. I've made it work but am not satisfied with the alignment of the 30mm PTFE tube that bridges the gap between the extruder and heat sink. The rendering shows the fan duct with optional part cooling, while the photos display my current rig with nozzle view. I find that as the part cooling channel is limited, it works well with PETG filament, which is what I mostly use now. If you've read this far, thank you. I hope you print this and enjoy it as much as I do. Stay tuned for the direct drive mount coming soon, which will utilize most of these parts (it will definitely use the hinged mount).
