Dowel Peg board holder

i was running out of space on my pegboard so i decided i needed some sort of easier system for all my pliers. using a 12mm dowel i made these to slot in. They are a very tight fit into the dowel and peg holes, to allow for almost zero slop. Also added in a spot for a grub screw to allow for a smaller dowel, that could be tightened, alto i have not tested that.
