Ender 3 Direct Drive E3D V6 Bullseye

Last crawled date: 4 years, 1 month ago

UPDATE:
It occurred that the mount itself is not strong enough to withstand fast retraction moves, which made it bend slightly. To avoid this, I added a smal rib to the fan mount which is connected to the extruder (see the white part in the newly added pictures). This prevents bending and I had no problems so far after extensive testing.
The new fan mount is called:
''New fan mount 40mm''
Direct drive, E3D V6 and Bullyseye fan duct? Say no more!
This simple but effective upgrade for your Ender 3 is mounted between the upper two x-carriage wheels and the hotend plate in place of the original wheel spacers.
Parts i've used:
E3D V6 clone hotend
Dual Drive Extruder (same designs from Aliexpress for instance should also be fine)https://www.amazon.de/gp/product/B07S7C4T7Y/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
Extension cable for the stepper motor (build your own or buy one)https://de.aliexpress.com/item/4000102135918.html?spm=a2g0o.productlist.0.0.5a7a13c7kXV6wa&algo_pvid=e32d726f-9653-4859-a125-b40864fbf2e4&algo_expid=e32d726f-9653-4859-a125-b40864fbf2e4-17&btsid=0d1e6d35-81de-41e0-97ba-540f09f1258b&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_53
If the motor turns in the wrong direction, simply switch the outer most cables with each other.

I actually had one lying around from another project and i think you can get them sold separately but i got mine as a kit:https://www.banggood.com/MK7-MK8-All-Metal-Remote-Extruder-Kit-For-1_75mm-Filament-3D-Printer-p-1026315.html?rmmds=buy&ID=519020&cur_warehouse=CN
I've attached the Solidworks files so that the design can be altered if needed.
