Who makes Mod 1.0 pinions for 3mm shafts?

[RcZoNe444]

A bore reducer would work and I might do that but do they only have shaft reducers for 3.2mm shafts? Some of the models I am converting are 1/10 and I am using 540 and 550 size motors that have 3mm shafts. But some other models that I am converting are going to use motors with 3.2mm shafts so I will keep that in mined.
