Say goodbye to warping and the noisy fans...
This mod work well with the hotend stock fan mounted on the I3 (also Mega-S,Mega-X). (E3DV5)
Only the extrusion cooling fan MUST be replaced by another model. (not necessary if you print only with ABS filament)
Update 05 June 2020 :
Files validated on Mega - X
Update 07 March 2020 :
Added Sunon Maglev extrusion Fan references
Update 15 January 2020 :
Following few requests, here are the link to the nuts and bolts used in this project

SpeedDrive documentation
Update6 -- EZR Struder now supported thanks to user Garigen
Update5 -- Geeetech A10 now fully supported thanks to user Cyg0r3
Update4 -- Ender 5 now fully supported thanks to user paydayxray and user stijoh
Update3 -- Redrex geared extruder now supported thanks to user huubert.
Update2-- CR-10s PRO extruder now supported thanks to a remix from user fsironman.
Update-- Added version for BMG extruder+stock/swiss hotend (also requires the longer endstop speedDrive_endstop_bmg)
The motivation behind creating the SpeedDrive mount was to extract maximum performance out of my ender3 with mostly stock parts. Print FAST with near-perfect quality. After pushing Bowden to its limit, I came to the conclusion (like many others), that sharp and accurate corners are simply impossible with a Bowden setup. Bowden setups are great for models with curvature, but for my particular uses, I was printing precisely engineered parts that often needed to fit together. Bowden setups produce poor corners because…
