RV Shower Shelf
thingiverse
So, those built-in shelves in RV showers are perfect for taking a shower but totally useless while driving. I designed these tracks to attach directly to your shower wall and then fit a piece of plexiglass into place. I picked up the plexi at my local Ace Hardware store where they even cut it to size for me. This design uses a 4-inch strip of plexiglass. You'll need to measure out the length you want based on where you attach the tracks. I placed mine an inch or two away from the shelf so that I could fit a bit more stuff on there.
