This is a mount for the 2015 RoboRIO. The RoboRIO is attached to the mount via 4x 4-40 by 3/8 countersunk screws.
This is a slight modification of the one that was printed by our team, as we had to drill out and widen the mount holes on out first print. If you print this let us know if we need to make the holes bigger or move them around.
