⚓ Belts
They will probably be cooked and not smoothy-circle, I am attempting to match new ones.
Everything in mm unless specified in cursed ".

There is also 4 open ones, two for each axis, width of 4mm, 2x21cm, 2x58cm, for a total of 158cm (1.58m).
They seems to match the profile of the two other axis so let’s assume they are MXL too, but in 4.76mm width.
