1" RAM Compatible Camera Mount for Maker Select IIIP

Mounts to the bottom front of either side upright of the Monoprice Maker Select IIIP. Two holes are 3.3mm thru hole to mount it, the others are 6mm to clear the heads of the bolts, so you only have to remove 2 bolts to mount it, so you don't disturb the alignment of anything. In the files, the pairs of matching holes are diagonally opposed (unlike the picture), which obviously makes more sense. The mounting pattern is 30mmx30mm square, so the ball can be position up or to the side.
