Lego compatible mecanum wheels

thingiverse

These are compact mecanum wheels that can be built using Lego components and support a Lego shaft. Note: If the rollers are attached with Lego, they should not be used in a drive system. They were created for use as a ball intake, which subjects them to much less stress. Also Note: The rollers must be wrapped in electrical tape (or similar) to give them sufficient friction to function effectively.
