There's still a little while to go before the Zheng3 Kickstarter's announced; we're in the video production stage now and hope to get the project out the door and into your retinas anon.
In the meantime, household exigencies require creative solutions, so to the MakerBot! we go with vim, vigor, and aplomb.
We don't countenance cable clutter in this house, young lady, so I put forth this wall-mountable clip specifically designed for the Nissan Leaf's 1.2cm diameter charging cable.
My experiences with our all-electric automotive future are documented at Zheng3.com.
And another Kickstarter teaser image. That's there too.
I recommend printing at high infill for this model. Glue the clip into the base before affixing to the wall.
The base is presented in eight different orientations.
Eveything's Better With Drywall Screws, so drill two pilot holes an inch apart and hang the base from a stud.
These clips aren't intended to support the weight of the cable's head or tail, but doubling or tripling up near those heavier parts may enable you to do so.
