White Knob replacement OR... a proposal

Hi! Does anyone have an encoder knob spare I can buy from them please? Just noticed my white one is mysteriously split below the white cap on the grey bit. So I would only really need the grey bit as the white-coloured part pops right off and is fine.

UK iFixit has a set of all OP-1 knobs including volume for just under 40 quid. If there are a bunch of people that fancy a new knob or two lemme know

Thanks!
