Shampoo/Conditioner Sample Holder for Shower

I get so many free samples, and they were falling all over the place in my shower, thought I'd try to make a quick solution! Bottom is open so it doesnt collect water.
Sized to fit in "Umbra Flex Hanging Shower Caddy"
60mm x 124mm x 50mm (height)

I used clear PVB and .4mm height. No supports but you may need a brim to prevent warping.
