Small wheel options

[WarehouseCrew]

Can anyone recommend some smaller wheels to try for the shooting mechanism? I understand team 3847 used Banebot wheels successfully, but I would like to hear if others have used other wheels that have also worked (and where you can buy them from).

If using a non-Banebot wheel, how are you mounting the wheel to your shaft (either gearbox or direct drive on CIM, etc.)? Most of the wheels I've seen are designed with bearings to spin freely on a shaft.

Thanks.
