Gear Shift Fidget Toy XXL - Print In Place

UPDATE 13.06.25: Some users have had issues because the shaft was moving while the knob was being printed. I have implemented some bridges that you must cut to prevent the shaft from moving during printing.

A huge thank you to everyone who downloaded my original design! 

Because of your amazing support, my first BambuLab printer is on its way! ❤️

I’m excited to share the XXL redesign of the model, as simply scaling up the original wasn’t enough due to tolerances and certain features becoming unnecessarily bulky.

This is a fidget toy that mimics a gearbox with the snap of each gear and the repositioning of the lever.

The design is fully print-in-place, so it requires no assembly. 

This new redesign includes:

• 🚗 A sleek new exterior pattern
• 🛠️ An improved spring design that resists deformation
• 🎛️ A more "car-like" knob
• 🔊 Incredibly satisfying snap fittings with minimal wear (seriously, it feels almost like shifting gears in a real car)
• 💪 A reinforced shaft that, thanks to the thickness, is now much more durable and won’t break.

Plus, you don’t need an AMS to print in full multicolor! I’ve included a print profile with optimized numbers and symbol for the knob, designed for easy part-by-part printing and press-fit assembly—no glue should be required.

I hope you love this new design. 

I’ll be reading all your feedback and suggestions for any tweaks or improvements needed. Enjoy!
