Summary

I printed a water cooler mount for the cargo area of my Knapheide work body. I got tired of moving it every time I wanted to refill my bottle. The mounting holes are sized to 7mm(1/4") and the side holes for the i-bolt bungee mounts are 8.5mm. The large hole is for access to bolts holding i-bolts. I suggest printing a few layers of the backing plate and canceling it so you'll have a jig to tape to mounting surface and drill through. I didn't and was off so my backing plate didn't line up and I had to drill a surprise hole. Not ideal.
