It's funny to think someone else had the same crazy idea!
An older version had 150 degrees of rotation. After play testing with a group everyone wanted less travel, 100 feels about right for most. Make the gear diameter larger and adjust the teeth on the rack for more rotation. Other dimensions will have to be tweaked to account for the larger gear.
Have fun with it!
