This is a fully custom design I made from scratch to cover the 240V extension cable that runs to my Tesla. It is a replacement piece for our cover under our door to fit the cable through.

Use version 5 as it is the most improved upon design.

Version 3- Improved cable pass through
Version 4- Improved dimensions and strength
Version 5- Added extra support under the middle area because version 4 would flex when full body weight was put on it
