Traxxas TQI thumb wheel with hole. Controller one hand Steer

Made adjustments to the design, adding a hole for a 3mm cable tie. Shortened the feature as my thumb became cramped while working on it. Found that my thumb kept slipping off, causing me to accidentally place the part in an uncomfortable corner position. To resolve this issue, I reduced the width to prevent slipping and smoothed out the end to eliminate sharp edges. Also made a slight reduction to minimize print time and material usage.
