Raspberry Pi Pan Tilt Camera for Exomy

This is a remix of https://www.thingiverse.com/thing:1799905 for the exomy rover (https://esa-prl.github.io/ExoMy)

Adjusted the case to make space for the camera flat cable to be inserted through the base into the rover's mast.
Modified the base so that it fits the screws holes of the mast.
