Mounts a Modern Robotics (MRI) sensor (IR, distance, etc.) to an Actobotics channel. Uses 8 square Actobotics nuts. Can mount the sensor outside or inside the channel. The 4 inner holes mount to the Actobotics channel and the 4 corner holes mount to the MRI sensor. Prints without support. Inspired by the MRI sensor to Tetrix mount at the following link: http://www.thingiverse.com/thing:996803
