A little while back I ordered an EVSE dummy holder from here : http://erroneus.myevblog.com/buy-plastic-parts-here/" onclick="window.open(this.href);return false; If you have your own 3D printer, you can print your own here: http://www.thingiverse.com/thing:154452" onclick="window.open(this.href);return false;
I was impressed by the quality when it arrived. Very sturdy plastic. Also interesting to see the way it was 'printed' layer by layer!
It was only available in orange for the ABS plastic version when I ordered, but it appears that black is an option now. I ended up painting it a color to match my house and mounting it near some other hardware hidden behind trees and bushes.
Now I don't need to constantly open and close my garage when I'm frequently charging in my driveway. I only keep it in the garage in more extreme weather or when I won't be charging for a few days.
