There is a really cool audio rack concept called the TNT FleXy Table that I felt would be perfect for disc golf. I built one for my audio equipment and was so pleased with the result I decided to step up my game for my second project and design a custom shelf add-on for discs!! It's super cheap, really easy to build, VERY sturdy, and totally customizable. I'm happy to provide any info or BOM details if anyone's interested...
