Earlier this year I purchased some Chromacaps for mine
I got the standard Encoder type in various colours. They did fit well but were a little higher off the enclosure than the stock ones, so left a small gap.
Being rubberised, they were so much nicer to use, but I really could not get over colours being too bright and primary school.
So I bought another set from chromacaps but all in black.
I keep toying with the idea of putting one of the colours back, maybe for the main encoder.
