Shower bar caddy

This is a shower caddy that hangs on a shower grab bar. It's big enough to hold a couple bottles of shampoo and a bar of soap, and has drain holes in the bottom.

Requires 4x M4x10 bolts and 4x M4 nuts. Ideally, these would be stainless, so they don't rust.

The two brackets are identical, but I uploaded them as separate files to make it easier to remember to print two of them.
