2x7 WallControl to 1x4 Gridfinity Adapter

A quick attempt at a mating of two of my favorite organizational systems. Uses sidepieces from aderusha's fantastic "DDD Printable Wall Controll System" (https://github.com/aderusha/DDD-Printable-Wall-Control-System)

Requires supports for the pins (I like trees) - print with the flat side down.

f3d provided in the hopes somebody can improve on it.
