I do have a 3d printer but, that one is currently sadly unable to print anything else than PLA (it’s a craptastic old anet a8) and I don’t know anyone at least close by who can do TPU. There is one thing I forgot to add to the original post, one additional reason I want to get something else than RCY is because of the jagged edges. They to tend to get caught in the fabric every know and then. But thanks for the advice so far, I will consider it.
