Ender 3 Direct Drive, all stock parts

thingiverse

I liked the idea of SpeedDrive of having just 1 part to print and not use anything that was not on the stock Ender 3, but didn't like that it reduces print volume. Also for me the small hole was too narrow to allow the screw to go through so i enlarged it a bit. This 90 degrees support allows for full print volume and still keeps the mass of the motor as best as possible distributed, but not as good as original SpeedDrive. Haven't tested print speeds more than 50 but i don't care for that. Only need to remove the left upper carriage wheel, and to put the bushing force it in with a plier or careful tap it into place, it's supposed to be tight. I haven't tried putting it in with a soldering iron but should work as well.
