f1 steering wheel buttons

[Mak0_0ne]

hello all,
im currently trying to make an f1 wheel- , specifically the mcl33 steering wheel- but want to find the closest buttons i can to the pics:
flat, round , 12mm , momentary buttons but with no cover or dome side lip- or removable cover. ive found the nkk or knitters a bit small, and im not sure the otto p9s have removable covers . does anyone out there know the closest buttons to these that are available please?
