MPCNC Lowrider v2 WHEEL

I bought all the parts by myself because when I saw the TT video, the "lowrider kit" was sold out and when I tested the Y planarity, I got "waves". I took time to notice that my chinese wheels were "oval", so I designed this 60/24mm wheels and I mounted them and now I got "round wheels"...

I put a washer between the Lowrider plastic part and the wheel, maybe it's not necessary.
