May not be such a big deal with belts, though.

To elaborate on this, the sideplates of this module were .125" thick steel plate, and there were also two pieces of adhesive backed HDPE between the module side plates and the inside tube faces to send the forces straight into the 3x3 tube.
The main reason I chose to pivot on the omni wheel was to keep the CIM hard mounted, rather than swinging with the module (single stage of gearing to the omni wheel).
