Holding one pair of calipers per every two inches was a bit too inefficient for my FRC team's tastes, so I redesigned a bit and now we can fit six pairs of calipers in 4 inches of space, by mounting them sideways.

If after printing, the pegs are too small to fit properly into your board, maybe try wrapping some kind of tape around them to thicken them up. If, they don't fit into the hole at all, take some clippers and trim down the outer edges of the pegs. I have also included the Inventor Part file so that you may edit it and make your own STL files to fit your specifications.

Remember to print with supports, and to cut the supports off when done printing.
