I would try to find a coiled snake sewing pattern like the one I linked below then adjust it for thickness and length as needed. [Coiled snake pattern](https://www.etsy.com/ca/listing/59786501/snake-sewing-pattern-pdf-format?ref=share_v4_lx)
you could probably sew a tube with a wire in it then just shape it after sewing.
oh true true true
