Soap holder for shower caddy

We bought a shower caddy (one of those things that hangs off the shower head and has storage for shampoo, razors, soap etc) but it really only had a spot for one bar of soap. My wife and I use different soaps so I decided to create a holder for a bar of soap that snaps over the railing of the caddy. The bottom of the holder has openings so water can drain out and a thumb slot to ease removing the soap when wet and slippery.
