Weighted Gear knob

thingiverse

I designed this gearknob for a 1994 Civic EG with an M10x1.5 bolt pattern, and you can modify the .ipt files to suit your needs. The gearknob's dimensions are 90mm x 31.2mm in STL format. A hollow center is featured on the bottom part of the design, which I filled with lead shot purchased from eBay. The weight of the shifter has not been measured, but it feels significantly smoother when shifting compared to a solid printed one. The printed thread for mounting the gearknob directly onto the car worked out well; I initially considered using a nut or threaded insert, but so far, this approach seems satisfactory.
