You are not allowed to take metal crochet hooks in the hand luggage of an airplane, but my wife likes to crochet during a long flight. Actually, a plastic crochet hook is also not allowed, but is allowed with a blind eye.
Because a crochet hook has to be smooth, I printed the crochet hooks in ABS and smoothed them with acetone.
Of course, a plastic crochet hook is not as robust as a metal crochet hook, especially in small sizes, but with a little caution it will work just fine.
I designed the crochet hooks in EU 2.5mm / UK 12 / US C2 and EU 3.0mm / UK 10 / US D3
