BRZ/FRS Shift Knob

thingiverse

BRZ shift knob with reverse lock-out cutout. Just print and go! Happy Shifting :) I've included the Solidworks file along with the STL, as I'm sure the extendo knob isn't everyone's thing. Recommended infill is 50% or higher. Testing below done at 80%, 60%, 40%, and 20%. From 40% and below, I've had failures in my testing. 60% and above is the surefire way to make it not break (in my excessive shifting force testing, I know I feel bad for my transmission too). Although above 60% seems overkill, it's mainly for weight more than anything. Official thread spec (will be tight but not so that it requires tools): M12X1.25
