My GoPiGo3 based robot Carl was marking up the floor with its stock metal ball caster, so I mounted this Pololu 1" Plastic Ball Caster in its place. The included hardware and shim plates worked perfectly to mount to the bot, (I did fashion a thin mounting plate from a plastic jar lid.) The new caster also contributes to the bot's improved rotational accuracy.

They are not cheap, but the ball rolls really well in the case. Especially with the enclosed dowel rolls.
Used the casters on a card caddy. Installation went very well using the thick spacer and small screws.
