Here’s my last version for the wheels blockout level 2:



It took me a lot more time than originally thought. I’ve done the modeling of the inner part of the wheel hub manually by eyeballing. Maybe it would be more precise using a plane orientated in the same way as the object in the reference image of the planetary gear and then tracing the outline on the surface while in perspective view. I’m still looking for reference images showing the connection between the wheel hub and the axle. Are the front axle and the back axle identical?
