Vertical Slider for Optical receiver

This is the new Vertical Slider for the Optical receiver 3-axis mount. It is used for the Optical Rail System, for mounting the receiver. The other parts needed to complete the 3-axis mount is the Horizontal Slider and the Tripod Mount.

The Rail Tensioner from Rob, K0XL is an option that is worth adding to the Tripod mount to securely mounting it to the aluminum rail.
