Simple Lid for piuLAB's Soap Holder

I wanted a soap dish with a lid, but I didn't find any on Thingiverse, so I made a lid for piuLAB's popular soap holder. I also saw in the comment for piuLAB's soap holder that others wanted a lid. I made a basic design. I tried adding curved edges, but I couldn't get them to work. I'm sure someone could make a sleeker design such as the soap holder itself.
