Sequential Shifter Tall Stick Replacement Gear

This is a custom sequential shifter replacement designed specifically for the SHH Shifter Thorn, intended for use in sequential mode, perfect for drifting and rally driving in sim racing titles such as Assetto Corsa.

The design follows the SHH 18×1.5 thread specification, with a 0.08 mm tolerance built into the model. The fit was snug on my unit but threaded on cleanly and seated perfectly. Thread fit can vary slightly depending on printer calibration and material, so minor tolerance differences are expected - I would recommend cutting the thread portion and printing that only to test fit the thread first to know your calibration.

If you’d like this model adapted for a different thread pattern or shifter, feel free to reach out and I can look at adjusting the design.

Please keep in mind this is a plastic shifter. While the design uses 4 wall perimeters and 25% infill, there is still a possibility of failure if excessive force is applied, particularly due to print orientation. That said, I have not experienced any issues so far, and it has been working very well for my intended use. Two versions are included: the original design and a more ergonomic variant - feel free to try either and use whichever suits you best.
