A mount for a z-axis servo to a x-carriage. This is not specific to any carriage. I just drilled a couple of holes to mount it on the carriage. The scad file is set for a Temco CN0097 micro switch. It's offset to have the roller inline with the pivot. 1/25/2014 Updated the servo mount scad file to make one that can fit a fan mount. Also, the z stop servo mount has been changed to shift the switch part to either side of the horn. 2/23/2014 Made the z stop servo mount thicker (4mm). Added countersinks to the mounting holes for the servo, the mounting screw would obstruct the lever.Print them. Trim the arm to fit the servo horn. Mount a Temco CN0097 with two 3mm screws. Drill two 2.5mm holes to mount the servo holder onto the carriage with two 3mm screws. Make sure the servo mounting screws are not interfering with the arm. Then modify the appropriate items in Marlin to use. I used a Hitec HS-65HB servo. The scad files are partially parametric. I recommend using a 7805 to supply 5v power to the servo. For the RAMPS, the Mega 2560's 5v regulator is near it's limit.
