Diamond Gear Shift Knob

This is a custom geometrically correct diamond gear shift knob! This product has a 4mm pilot hole drilled 25mm up the center for tapping to your correct size. The pilot hole can be expanded upon request. For best results I recommend getting it printed in something metal becuse this knob is made to be heavy to throw into gear.

Extensive testing was done in PLA, ABS, PET(G) and Nylon before uploading a finished model to shapeways. I currently have a black PET(G) shifter in my Mazda Miata.

**Plastic models may not drill and tap well, in this case, upon request, I will modify the design to accept a nyloc hex nut that will thread onto your current shift rod. All I need is the size in MM that you want the hole made to. The customization is completely based on your measurements, so measure twice before you order!**

Custom orders are avaliable!
