This model is designed for the Jeep Wrangler TJ with a 5-speed transmission and JK with a 6-speed transmission.

TJ: Features a 10mm hole that will thread itself upon first installation.
JK: Ball diameter is 70mm, with a 12mm hole at the bottom. It is recommended to use a shift knob adapter from Amazon, as the JK stick is notched. Note: The center hole may need to be enlarged slightly for a proper fit on the stock JK stick.

The ball is rather large and comfortable to hold. I use 20% infill, but it could likely be reduced to 15% for material savings.

I hope you like it!
