Remix of LittleGreenFire's excellent pegboard design adding a Wire Hanger, mounting holes to the wall clip, a short peg option, inside trim edge pieces, and an outlet trim-out.  I preserved most of the parametric design, however the final exterior trim pieces will likely require a cut in your slicer of choice to fit your overall design and the outlet trim-out will need to be customized.

Note:  Most of the design's STL files can be found at LittleGreenFire's page.  I've only added the components I created.
