Printed the OmniWheelSolid.stl with Robot Gray PLA and the Barrel.stl with Ultimaker Flex PLA. Sanded the Holes for the axles in the wheel a bit bigger and then put everything together with Lego Original axles.
Fits perfectly and runs smoothly. Thanks for the amazing design. I am gonna print some of your bigger mecanum wheels in the future for my little test bot.
