EV plug cap (with retainer)

Oh no, not another electric car type 2 charging plug cap! Well this one incorporates a tether string and cable clip. so is a good all in one solution. It must be made in TPU or similar flexible and durable material. PLA will just break. The wide flange on the cap makes it easy to remove from the plug and also prevents the protected plug body rubbing against the wall.

I have included 2 files (3 now see below edit). One with water drain vent holes and one without.
If the plug is located outside and is to hang downwards, please use the vented one. Otherwise it will fill and pool when it rains and will cause electrolytic corrosion to the pins (especially the CP pin which always has 12V present!).

UPDATE EDIT. I have recently improved the cap with the drain holes (V2). It fits plug better for easier fitting and removal, has a shorter tether and larger drain/vent holes. Also has larger size cable clip on the end of tether and hangs in a more convenient natural orientation for fitting
