I use my caliper often enough that I put this together this holder to keep it handily stored on a pegboard.  It is designed to fit the "Pittsburgh" low-cost digital caliper from Harbor Freight, although I suspect it would work with other similar models.My pegboard is 1/8" thick, with holes of approximately 3/16" diameter at 1-inch spacing.  I believe this is a pretty standard configuration for pegboards, but you may want to double-check your pegboard is similar to ensure this will fit.  It does NOT work with the thicker 1/4" pegboard.Note that you will want to have supports turned on when printing.
