This is a steering knob for a 2000 to 2005 BMW e46 or any with the steering wheel that is pictured.
Slicer screenshot is the correct orientation for all parts
Supports are needed.
Solid is preferred.
Print in something vehicle interior safe.
Walls and top bottom layer thickness need to be high if you don't make it solid.
The only differences in the housings is the length of back piece (I use the short one, but the long one hides the screw better).

You will need:
1) 1 #10 by 2inch Phillips head machine screw and accompanying nut (locking or standard will do)
2)1 6806-2rs bearing (This is the main bearing the other is not technically needed unless you are making a heavy duty version. I had room to add it so I did.)
3) Sticky back felt or the soft side of a Velcro tape strip in whatever color you choose
4) Optional 608-2rs bearings for if you are heavy handed or drifting. (Do not use only this bearing it will break quickly.)

Assembly:
1) The nut will be heat fitted to the botto
