Hi, these are sift knobs I designed, they are tapped for Honda threads

one is dimensionaly correct to my Mugen F1 shift knob

2nd is dimensionaly correct to the NA2 NSX shift knob

Last is a design inspired from the new Mclaren t50

These are 3d printed but look very good if you sand them smooth and paint or clear coat them.

Please choose your style and desired color
