These Omni-wheels are great but the associated CAD has measurements that are slightly off
My team purchased these wheels and are very happy with them. Prior to receiving the wheels the team designed custom hubs and 3D print them based on the CAD for the wheels. The dimensions (primarily the depth) were off my about 1.5 mm which required the hubs to be reworked and reprinted. Overall the team is satisfied with the wheels and would purchase again.
