Anet A8 Dual Bowden Conversion

In an effort to gain more accuracy out of my printer, and gain the ability to print in dual colors, I've come up with this design.

I also felt that I would be able to gain some printing speed by decreasing the moving mass on the print head.

I've tried to keep the hot ends as close together as possible, so as not to lose build space. Both nozzles have access to the entire build plate.

Also, the auto level servo mount was designed to not lose space or interfere with the side of the machine. You MUST route your heating and thermistor wires carefully so that they don't hit the frame when homing the X axis or on the far side of the build plate.

This design, like several others, deflects hot end cooling air out the sides of the mount, keeping it away from the build plate.

I also have found that most small servos have quite a bit of slop in the gear train. Most of the servo arm designs I've seen have the button on the switch offset from the center line of the servo shaft. When
