Been busy with work but finally got back to the shifter. The throw length is about right with the knob mounted fully onto the shifter as shown below. I also filed the top edge to give it a more natural feel in my hand.
Planned design changes: deepen the mounting hole, add more chamfer to the top edge, thicken the walls and internal honeycomb for more strength, and add a reinforced boss for a flanged expansion insert/retaining screw. Then I'll print Version 2 in a more appropriate color (white or black) sometime this week.
