My original horn button was the “slip in” button, which didnt hold very well and would fall out often. It also didnt look very nice. 

This is a replacement which uses the 6 bolt holes from a 6 bolt steering wheel to hold it in. 


You will need to use the internals from a working horn button to make this functional. This would include

  • Spring and clip which grounds to steering wheel body
  • Cup which makes contact with the spade connector
  • Spade Connector itself (only 1 is needed for metal wheels)

To remove the old spade connector, i heated with a soldering iron and pulled off, doing the same in reverse. 

The button clips in, in a single direction so match the arrow and notch when assembling. 

 

Print with the button face and the outer face down. You can print with supports inside to get a solid base, however i didnt use supports and my Prusa MK3 was fine, just a bit “hairy” inside which cleaned up easily. 

Once installed buttons works perfectly. 

 

Included the F3D file so you can customise, possibly, add inlays, or make a holder for a enamel badge.
