I wanted a better cargo holding method for the Rivian R1T’s front trunk. The OEM solution is a simple elastic and mesh pouch against the front wall of the frunk, and it’s almost good enough. I had a few requirements, like gaining the ability to stop grocery bags from sliding around, spots for storing a supercharger adapter, and expandable storage for random items I’d need to carry.

I started with a quick 3D scan of the front trunk, and a bit of CAD in OnShape:

I had to remove the OEM mesh bag pegs, and in their old holes I was able to install rivnuts. The MOLLE panel has some 3D printed standoffs, but bolts to those rivnuts with some M6 stainless torx pan head screws (aka perfection in fastener form). The MOLLE panels themselves are 0.125" 5052 aluminum, laser cut, bent, and powder coated by OshCut.

I used some tacticool pouches to hold my supercharger adapter, some pens, trailer hitch plug adapters, and other things one should keep accessible in a car.
