Some time ago, I came across a very cool object on Thingiverse: a keychain with 2 gears of different sizes, that rotated connected to each other. I didn’t think twice, I 3D printed everything and started using it as my personal keychain. However, after a couple of weeks, the rods that hold the gears hubs started to break. 3D Printed a new object but, another time, after two or three weeks, it broke again more or less in the same place.
I then decided to make a small modification to make it stronger, increasing the width of the rods.
I demonstrate the process of changing this object in the video (Portuguese only – at least for now) below:
This change is available on my Thingiverse profile at:

Original object (with gears and all):

I hope this tutorial is useful 🙂
