3DPrintedCarPartDescription
This is a custom horn button I made for my RX7's Momo Nero steering wheel. It replaces the center horn button and brass dome insert. You will need to apply a layer of aluminum tape and two m6 washers to ensure proper electrical contact. The logo and horn symbols are raised 1.6 from the button surface and printed in PETG. This was also scaled down from 45 mm to 42.8 in order to fit inside the momo horn button assembly. It is strongly recommended that you use a caliper to measure the horn button you are replacing. I also included a horn symbol STL since the original Momo button has that symbol.
