Ender 3 Max Direct drive

Direct drive for the Ender 3 Max

There are 2 carriage styles, one with a Bowden tube connector (recommended) and one without a tube connector.

(Original carriage file from here, https://www.thingiverse.com/thing:5191840).

I modified 40x40x20 fan shroud (the original can be found here, https://www.thingiverse.com/thing:4902320).

I added an x-stop extension block to keep carriage from hitting frame.

I have included 2 sizes of Bowden tube connector plates to replace the original extruder to preserve the runout sensor function.
Bowden connectors are M6 thread or M8 thread, extruder bolts are M3x12mm, and M3 nuts.
