My team is looking to purchase magnets for our minibot.
The diameter of the Tetrix kit motors is ~34mm.
We have found two sets of motor magnets with different inner diameters:
28mm:

39mm:

Should we go with the smaller set or the larger set, or is there a better-fitting set anyone else could find?
