This model is not currently offered as a verified ready to buy print.
What it does
- Fully working differential gear lets you see car mechanics in action
- Hands-on learning tool for understanding how power splits between wheels
- Multi-part assembly project, great for hobbyists and STEM education
- Features authentic bevel gears for realistic mechanical demonstration
- Perfect desktop demo for gearheads, students, and curious tinkerers
Ever wonder how your car's wheels can turn at different speeds while going around a corner? This functional differential gear system brings that engineering magic to your desktop. With a single input shaft driving two output shafts at independent speeds, you'll get a hands-on look at the same mechanical principle found in most vehicles on the road today.
This multi-part educational model features precision bevel gears that mesh together beautifully once assembled. It's designed to be both a learning tool and a fascinating desk toy, spin the input and watch the outputs respond. Whether you're a student diving into mechanical engineering, a teacher looking for a killer classroom demo, or just someone who loves understanding how things work, this differential gear model delivers.
The design faithfully recreates the core mechanics of automotive differentials, making abstract concepts tangible. Assembly required, but that's half the fun, you'll understand every component as you put it together.

What it is made of
Designs like this print well in PLA. Compare the materials.
Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
