I love sim racing but hate overspending.
Most cheap handbrakes online go for $100+ — despite being super simple and often poorly designed (buttons instead of potentiometers, too many screws, inconsistent parts).
So, I designed my own: a low-cost, 3D-printable handbrake that’s easy to build, durable, and feels great.
- Build cost: Under $20 CAD
- Material usage: <100g filament
- Full potentiometer range for smooth input & compatibility
- Simple design → minimal screws, no glue/tape required
- Printed in PLA on an Ender 3
- Strong, reliable, and fun to use 🎮
- Arduino Micro / ATmega32u4 / Teensy board
- 10K potentiometer
- Extension spring (60–90 mm length, ~10 mm width)
- Desk clamp
- 1 × M5 screw (10 mm)
- (Optional) Electrical tape
All STL files, assembly steps, and detailed instructions are available on Thingiverse:
- Designed to be hand-soldered and tinkered with.
- Lightweight but surprisingly tough.
- A fun, practical project if you enjoy sim racing and DIY electronics.
