Great model. I printed this in multiple sizes. I'm still fairly new to printing with TPU. I had some trouble with TPU 95A HF (yellow), but that easily could be something on my end. It was new filament and I did dry it at 65c for 18h. I had near perfect results using TPU for AMS (blue). This print was on my H2D so I used PLA for support out of the second hotend. I set the threshold angle to 0 and the top z distance to 0mm. This made the curve at the bottom of the bag very clean. If you decide to change the size of the bag, you will likely have to play with the scaling for one side of the buttons for the strap. I recommend printing one button set for a test.
