Rally shifter Version 4. The radius on the top edge is perfect for comfort in the palm of my hand. The mounting depth looks and feels right. Created a center slot instead of a circular hole for better mounting. The walls and internal honeycomb are thicker so it has a nice weight and feels super strong.
I'll drive it like this for a bit and if all is well, then I'll add an insert for a set screw to hold it firmly in place and call it done. Set screws are easily sourced from McMaster-Carr.
