Description

Enclosure for a Blue Sea Systems Panel 4363 designed to mount to existing holes in the roof of the Tesla Model 3 trunk. I recommend printing this in PETG to avoid issues with heat warping as the trunk of a car can get quite hot. Print with the side with the single small rectangle down on the plate (large opening straight up), and then use supports everywhere to ensure that the mounting slots remain intact. For more info on the full installation, check out this post: https://teslamotorsclub.com/tmc/threads/added-12v-outlet-in-the-trunk.272997/
