MF 231S Steering Wheel Center Cap

thingiverse

Got this idea after seeing the Massey Ferguson badge submitted by @dan_d_builder. Using MS "3D Builder", I loaded the badge file and added 3 "cylinders" beneath it in order to create a "groove" for an O-ring thinking I might need the O-ring to make a tight fit when inserted in the steering wheel. Using "3D Builder", I changed the x and y dimensions of @dan's badge to 60 mm in order convert it to a round object with z dimension of 6 mm. Being my first time using the 3D Builder software, I just stacked the badge on top of the 3 cylinders with z dimensions (thickness) of 4 mm, 3 mm and 3 mm top to bottom and x,y dimensions of 49.15 mm, 44.55 mm and 49.15 mm.Turned out it fit "snug" enough in my steering wheel, so I did not even need the O-ring. If you do need to use an O-ring, the groove was designed for a -132 size O-ring.
