They said you can't build a whoop with a TPU frame, but I had to try, and it worked! I modified a design from Thingverse and went through 3 iterations, but it flies. Not the spry-est quad in the world, turns out TPU is a bit heavy, but it is durable.

For the canopy, I took a betaFPV whoop canopy and made a resin cast of the inside, then used that to vacuum-form my own canopy out of yellow HDPE on a Mayku Formbox.

The rest is kinda standard whoop parts.

Here's one of the first flights:

And here's a testament to durability - I slammed into a tree:

That TPU Frame is pretty sweet.

Thanks! Sorry to say it looks better than it flies. Mainly because it's heavy, and I think that higher-g turns deform the frame more than a polypropylene (PP) frame would. I think PP makes the best whoop frames: they're durable and light.
