The parent system is neat, but I needed a way to mount these IRWIN wire strippers: https://www.amazon.com/IRWIN-VISE-GRIP-2078300-Self-Adjusting-Stripper/dp/B000OQ21CA
Additionally, I found some of the sidepiece flats and pins in the parent to have hooks that were too tight in the slots, and/or too loosely fitting with the centerpiece pins in a variety of different filaments, so I needed to alter some of the tolerances.
I recommend printing the left/right flats presented here instead of the ones in the parent, as i've altered them not to catch on the wall-control panels, and i've also altered the pins and holes to fit better, particularly if you plan on super-gluing them together to form single solid parts.
