Ender 3 Dual Gear Direct Drive Adapter

thingiverse

Hello everybody!This is an adapter to fit a dual-gear system onto the official creality ender3-direct-drive x-carriage.My problem was, that the aluminum parts of the dual-gear system didn't fit the old x-carriage.So I made 3 parts:DirectDriveSpacer - needed between the x-carriage and the extruder motor.baseplate - needed between the dualdrive-system and the extruder motorarrestingpin - needed to arrest the pin (as we have to leave the screw out for this adapter).I printed everything out of standard PLA and worked fine since 50 print-hours. There are some minor wobbles - but nothing to decrease print quality. If you can, print in a stiffer material - but PLA is fine for me for now.Build needs 2 M3 hex-nuts and 2 M3 screws to lock the DirectDriveSpacer onto the x-carriage.Order to assemble:Fit baseplate onto extruder-motorAdd the dual-gear system on top of thatInsert the arrestingpin to lock down the springScrew the DirectDriveSpacer onto the extruder-assemblyScrew everything to the x-carriage. If nuts are too lose - either retune printer or I added a blob of hotglue to hold it in place until the screw is tightend.Good luck! I hope you have fun with my design! Took me a few hours to fiddle around! :)
