Ender 3 Direct Drive E3D V6 Bullseye

thingiverse

UPDATE: It turned out that the mount itself is not strong enough to withstand fast retraction moves, which caused it to bend slightly. To prevent this, I added a small rib to the fan mount that is connected to the extruder (see the white part in the newly added pictures). This prevents bending and I have 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 should also be fine) https://www.amazon.com/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://www.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 outermost cables with each other. - Bullseye Fan Duct https://www.thingiverse.com/thing:2759439 - L-shaped motor plate: 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.
