Mini Spool For Motor

This is a spool that I designed is for a six volt geared dc motor. I have two versions of my spool one is V1 and it is for a shaft that has flat spot parallel on the shaft. V2 is for the more common shaft for a motor like https://www.amazon.com/Delaman-Gear-Motor-High-Torque/dp/B07R8VMD42/ref= it is a d shaped shaft. I provide stl's where they are all together or seperated (first 2 are grouped and the rest are ungrouped) I designed this spool for my claw machine that is still a work in progress.
