Finally a pleasurable task: assembling rover wheels!
With all parts needed for one wheel hub printed...
... we can proceed with assembling the wheel hubs! Here are parts needed for one wheel hub along with tiny motor and AS5600 sensor on breakout board, along with printed wheel hub with copper rings:
First there's motor lid with the guard, second row shows motor holder and how motor is wedged in and on the last row we have completed motor holder.
Now we can add the wheel to the motor shaft, and put the motor holder (without the lid) into wheel hub and then secure all with the lid.
Next is to add bottom of holder for AS5600 sensor and secure it with a lid. Lid would keep that part of the hub secure and keep AS5600 in place.
And finally - this is how rover now looks viewed from the bottom:
