Gear Shift Fidget Toy V2 // Print-in-place

After the great success of the Gear Shift Fidget Toy (thank you <3), I’ve created the V2 to address many of the issues that users have experienced. Update 8/9/25: New Spring Cover Available!

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, requiring no assembly.

It retains the same shape but includes several upgrades for improved durability, reliability, and faster printing.

What’s New?

- 🆕 Updated pattern and knob design

- 🛠️ Redesigned spring to better resist deformation

- ⚙️ Improved snap system that reduces wear on each gear

- 💪 Stronger, more stable shaft that stays secure during printing (tested on Voron, KP3S, and BambuLab A1 with various filaments, including multicolor printing)

I’ve included 4 versions:

- Default, should work on 95% of printers

- Keychain, it has a hole so you can use it as a keychain

- Looser, for those who find the gears too tight; you can try printing this version (available in the print profile and CAD file)

- Tight, some people have found that the third and fourth gears stop engaging after a few minutes. This is due to differences in flow/tolerances of the printer. This version has tighter gears to ensure they hold for longer.

Recommendations:

- 🧼 Clean the print bed thoroughly to ensure the spring adheres properly

- ⚠️ Be cautious when removing the print from the bed, as the shaft may stick and deform the spring: avoid pulling; gently flex the build plate instead

- 🚫 No supports are needed

- 🔧 Enable Z-hop if you experience issues with the shaft shifting during printing

- ‼️ If not using a print profile: Ensure the seam of the shaft’s spring isn’t too close, as it may fuse and affect functionality. Try setting the seam to “back” or rotating the object

I hope you love this upgraded design! I’ll be reading all your feedback and suggestions for any tweaks or improvements. Enjoy!
