Steering Wheel Spinner Knob for 29x36 mm Wheel

thingiverse

My wife had shoulder surgery, and she needed help for many months. The original FULspeed design wouldn't fit our steering wheel, so I modified the files to fit the non-round 29 x 36 mm steering wheel in my Pontiac. I replaced the knob pivot bolt with a 5/16 carriage bolt and adjusted the knob and cap to accommodate a nylon lock nut within the cavity. I also used sheet metal screws threaded into the bottom half instead of metric through-bolts and nuts. This really made things easier for my wife, and I find it useful too. My thanks go out to FULspeed. As mentioned in other similar projects, the legality question and the risk involved in having this attached to the steering wheel rest with the user.
