Shift Knob Subaru Reverse lockout

I was inspired by

But this knob is designed from scratch. it works with the STI 6 MT reverse lockout. Printed with 100% fill

This is a slim Knob. i will be uploading more when i finalize the design i wish to use in my project

I heated a 12 x 1.25 bolt and threaded it in the base, spinning it while the bolt cooled cured the threads while insuring straight fitment. I then placed the bolt in a drill and sanded at 120, 600, 1000 and finally 2000 grit for a smooth finish
