I like to keep the J1772 adapter in the cubby under the main display for quick access. In there, or in the glove box or "bowling alley", it rolls around like crazy. So I made a square for it to stop it from rolling.
It can be made in pretty much any material or color, but I only picked a few of the cheapest and sturdiest. If you want something else, let me know.
I put the Tesla logo on it because it was easy and fun and actually saves a little material. I'm not making any profit so I can't see why there should be a trademark problem.
