I attempted to print this in 95A TPU and it was not quite flexible enough, reducing the height and wall thickness might help for 95A or using a lower shore hardness TPU may help as well.
If you would like to customize the size you can download organizer.scad and honeycomb.scad into the same folder and edit organizer.scad , there are some variables at the top to change width, depth, and height, honeycomb wall thickness, bolt hole size, etc.
