Looks great, and you will find it flexes to comply more in 1 direction. Just a word about printing it, know that the shells on tpu become much more stuff than the infill. So when you print it, you may find you want to round more of the edges to get flex in different locations. Can’t wait to see it in action.
Would you be willing to share the step file as we have been trying to do the same but with TPU entraption stars. We would gladly relay all info gained from them as it’s difficult to look at pros and cons of them without testing them.
If anyone wants to try a custom infill with nTopology, I would be happy to generate a file for you. It only take a few seconds to import a model and apply any number of lattice structures.
@CoubardAlex I generated an entraption star for you based off of the standard AndyMark star and attached it to this post. Let me know if you want changes or have a different geometry you want to try.
