I couldn't get other bearing cover models to stay in place for long despite a few scaling attempts, so I decided to try a different design.
The outer diameter is slightly oversized to be tight against the wheel hub.
The overhang shape should allow the cover to remain away from the bearing inner race.
I printed it in TPU.
Place some grease between the bearings and the covers for better efficiency.
