GeekDrive - All in One DirectDrive extruder adapter with best CG and shortest path to Nozzle[Ender 3/CR-10]

thingiverse

#Direct Drive Extruder Adapter - GeekDrive # The Direct Drive Extruder adapter has the best possible COG with the Stepper motor mounted ~3mm above the frame, and the shortest path to the Nozzle since it's directly fed into the Nozzle. ##Important: Because of tight tolerances, I recommend printing this part at high quality. ## I highly recommend upgrading the pulley wheels to Polycarbonate type to reduce wear from added Mass of direct drive design, which is a great upgrade for Glass bed owners too. Link to Polycarbonate wheels including bearings: https://www.banggood.com/custlink/3Gvmfl95mn ##Regarding BMG Extruder: I hope to receive mine soon and then I will make another version to integrate their design into my carriage plate. I must have the part to test it myself before releasing, so I hope it won't take long. This mod replaces the X carriage and the stock extruder and combines all in one part. The X carriage plate has many M3 screw holes for designing your own attachment (BLtouch/Fan ducts... etc.). ##Bed Size After Installation: X:230mm. Y:230mm with new Y_LimitSwitchBracket installed. Z:~150mm until you install Direct Driver extension stepper cable. #Assembly Guide Album:# https://imgur.com/a/H8MSkxg Make sure that the eccentric nut goes in like in this image - the hole is tight fit.  #If you like to get 5015 Blower Fan Fan Duct- look Here : https://www.thingiverse.com/thing:4498768 Note: E_Housing.stl won't be compatible with this fan duct. #Important!# After first installation, make sure to Re-Tighten the Pulley Wheels screws after first week of use - because printed plastic can have tiny gaps and after first week the screws can feel little loose, after 2nd re-tightening it should last for long time, just keep an eye if the screws become little loose every 1~3 month. ##I hope you like it and please feel free to design better fan Duct's to attach to the M3 screw holes on the E plate :-). #Updates:# ________________________________________________________________________ Update July 17th: Added Eccentric_Nut_Custom-Tool.zip to replace stock Eccentric Nut with larger model to help against deforming, you can use Drill jig on your already printed E plate and drill with 10mm drill or print newer "GeekDrive_E_Plate_Custom_Eccentric_Nut" E plate, when assembling - you gonna need M5 Large washer under the Nut on the Eccentric wheel. Important Update July 15th: Craftrum_5015_FanDuct_RemixFor_GeekDriveV3 was deleted because of desing error in part, Replaced by newer Craftrum_5015_FanDuct_RemixFor_GeekDriveV4 that fixed problem. Added GeekDrive_E_Plate_M3_Thread_Inserts and RadFanMount_M3_Thread_Inserts with 4.1mmx6.7mm holes for Brass M3 thread Inserts. Update June 27th: Added a better V3 design to reduce air outlet deformation. Update Jun 25th: After many of you asked me for 5015 fan ducts, I have modified the CRAFTRUM 5015 Fan duct by Holyfarrier to be compatible with my design: https://www.thingiverse.com/thing:4498768 Update Jun 21st: Added Assembly Guide: https://imgur.com/a/H8MSkxg Update Jun 21st: Added PartCoolerMountBodeyV3 with better design -better aim on nozzle tip.. Update Jun 19th: Added E_Housing.STL for cleaner finish look. Added PartCoolerMountBodeyV2 with better design. Added RadFanMountV2.stl with better design. https://imgur.com/aMbgDwa Update Jun 18th: Please replace stock Y limit switch bracket with new modded one Y_LimitSwitchBracket to get 230mm bed size on Y Axis: https://imgur.com/C70s1w5
