This model was a blast to make. All of my previous bag holders were installed with screws, and I wanted to make a design that didn't require that. I went through so many different iterations on the hanger design. I wanted them to be lightweight, strong and connect easily. After dozens of design changes and tweaks, I was finally confident. There were rounds of load testing, measuring the deflection and improving the structure. I only release models when I'm confident they're ready to last years.
