Anet E12, E10 and others; X-Axis upgrade.

I wanted to overcome the shortcomings of the Anet E12 X-carriage.

I have tried a few, and they have failed, most move the lower wheel to the middle, this is fine if you can make the carriage out of metal. If you print the X-carriage with the lower wheel in the middle, then the heater block can soften that mount, and the wheel bolt starts to tilt, and the carriage comes loose.

Well here is one way that doesn't cost much just time and effort.

Here is what this upgrade project will need.
