Using #0190 wheels with GM11a

I thought I’d post my attempt to mate the GM7 wheel (#0190) with the new GM11a motor. Since the wheels are designed for a splined 2mm shaft and the GM11a has a 2mm shaft I thought this combo might work well. As it turns out the GM11a has a knurled shaft, not splined, so the parts don’t play nice together. :frowning:
