so i made the top part of the crank which has the grub screw holes and the space for the motor. this was pretty tricky, and i had to graph out the the motor hole in desmos to make sure i got the dimensions right. My dimensions ended up failing after i finished it as it was a bit to short, so i made it longer and instead of needing grub screws it just friction fit perfectly this took a while idek why probably an onshape skill issue.
