Clamp for Z Axis Depth Indicator (Prusa i3)

I really like the indicator that http://www.thingiverse.com/thoxbui posted a while ago.

I want to make similar one that can hold dial gauge instead of digital gauge.

Since thoxbui posted only stl file, I had to design my own in openscad.

X-rods spacing is 45 mm. Rods are of 8 mm diameter.

You can utilise my scad file and put any probe mount on it.
