EDIT November 23rd 2017:
I recommend printing the hanger clip (small part with two holes in it) at 98% scale. (2% reduction in xyz uniform direction). The dock it self should be printed at 100% scale.
Cable management hanger for Tesla EV plug (Type 2). Plug should be inserted at an elevated angle and lowered to ensure proper locking into the internal latch. See pictures for reference.
Update: added mkIII stl files. This one comes with a Tesla logo and less material usage overall. Note: I have not personally tried printing the mkIII version yet, so I'm unsure how well the internal hollowing will work with angles and bridging.
Print with whatever settings you'd like. But, for best result, print at an 30 degree angle. The surfaces on model that should be at layer 1 is highlighted in the third picture attached to this thing. Supports needed in order to support the internal latch retaining the Type 2 EV plug in place. Bridging is not possible.
I recommend no more than 5 to 10% infill as this model is quite large.
2 to 3 shells should be sufficient.
