These are the brackets that are needed if you want to add the false floor in the cargo area/trunk of the Chevy Bolt LT.
I found this model online but I can't find where I found it again to link to. I did not create this model. I remember it took me a long time to find a decent 3D model of these brackets to print, so I wanted to upload them here to make it easier to fine.
