Is reference to split CC2 caps - can't find example in repo

[Vaelatern]

This video https://www.youtube.com/watch?v=geRvMmrd5n0 refers to a keycap split like my CC2 has - stem + cap. I see the stem extender in the repo here but the full assembly STEP doesn't have the keycaps that use this bit, it has the original CC2 keycaps.

Any chance of seeing the CC2.1 or CC2 tops?

(My rubber ring just split the left paddle on a layer line so I'm trying to print a replacement).
