BRZ shift knob with reverse lock-out cutout.
Just print and go!
Happy Shifting :)



I have 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 have had failures in my testing. 60% and above is the surefire way to make sure it will not break (in my testing of excessive shifting force| i know i feel bad for my tranny as well). Although above 60% seems overkill, it is for the weight more than anything.

Official thread spec (will be tight but not so that it requires tools):
M12X1.25
