About this 3D model

This design is based on [Servo mount for auto bed-leveling for Prusa i2 X-Carriage](http://www.thingiverse.com/thing:194012). I changed the following: * Parametrized the SCAD source. Tweak it to make it fit your servo, X-carriage and hotend exactly. * This servo mount can be printed longer or shorter, matching your hotend. The original is too short for E3D v5 hotend. * Servo mounting holes are smaller, to match the smaller holes in most micro servos. This mount will fit most X-carriages with 10x10x15mm accessory mounting block. In particular, I'm using [Reinforced Prusa X Carriage with Slim LM8UU Holder](http://www.thingiverse.com/thing:18657). The micro servo I'm using is TowerPro SG90, but SCAD file can be adjusted to fit other servos with slightly different dimensions.
