One of the most useful but hardest to find bits of pegboard hardware is the pliers holder, like the one pictured. It's very simple, but all the hardware stores I've visited only have them in these huge assortment packs with way too many of other hooks you don't need. I've found a few sources to buy them online separately from these assortment packs (e.g., http://www.hardwarestore.com/plier-holder-pegboard-hook-us2c-628413.aspx), but the shipping prices always make it ludicrous. So, here's my homemade one. The design is a little different from the metal ones, both for strength and ease of 3D printing, but the effect should be the same. This is sized for a type A pegboard (1/4" spacing).You'll need to print with supports; be careful while cutting them away to avoid weakening or breaking the legs. I'm stumped for a way to avoid supports on this and still have it have the strength to hold up pliers.
