A Bit on PVCPVC is inexpensive and readily available. It's also fairly lightweight, though it can get quite heavy when used in large quantities as I did for this project; still, it was the best material choice for my needs because I don't have unlimited funds!
If you need simple, straight shapes stuck together, you probably won't need to bend anything at all. You can take advantage of the many types of connectors they make for PVC. Just be sure to glue them together with PVC glue, which is in the same aisle, or something else to ensure they don't pop apart on you!
