I created this to solve a problem: My family hangs their toothbrushes on a rack in the medicine cabinet in our bathroom. After brushing my teeth we rinse our brushes and hang them on it's rack. However over time the drips off the rinsed brushes start accumulating on the wood shelf in my medicine cabinet.

So to protect the shelf from water damage, and some incompletely rinsed sediment (toothpaste) I designed this tray.

For my use I measured the dimension of the shelf, and because it is longer than my print bed, I split the length in 3 and printed 3 trays.

This way the trays can be washed and replaced when they become gross. I made it customizable so that it can be modified to fit other situations.
