My laundry bag stopped standing up on its own so I designed an inner frame taking reference from what I saw on Google. Google gave me the idea to use PVC pipe and connect them like a 3d rectangular prism. I was told this part wasn't made and so 3d modeled it and then printed it myself. Later learned they were manufactured but did save myself some money, oh well. If you want to learn more check out my Printables or Instagram page!
