Practice: Direction Swap
A 1:1 gear pair that reverses rotation — one motor, two shafts spinning opposite ways.
01
Direction Swap
Model a 1:1 gear transmission that inverts the motor's direction.
- Useful when two shafts must spin opposite ways from one motor.
- A pair of equal gears flips direction with no reduction.
- Practice with plates, spacers, shafts, and belts.

Spacer Choices
Three ways to make a spacer.
- 3D-printed: fast and free.
- COTS aluminum: strong, off-the-shelf.
- Custom fabricated: when you need an exact length.
Recap
DIRECTION SWAP
- 1:1 gears reverse direction, no reduction
