DIY Sim Racing Pedals
Print Profile(3)
Description
Sim Pedals – DIY Construction
These self-built **Sim Pedals** are a robust and cost-effective solution for use in racing simulations. All parts are optimized for 3D printing and can be made with commercially available filaments.
Throttle and Clutch use Hall sensors
Brake uses a 200kg Loadcell
Updates:
02.04.2026: Added Assembly Guide
29.01.2026: Added electrical schema in the project files.
21.08.2025: Added the HallSensor Mount & Arduino Code.
29.08.2025: Added support for 40kg Loadcell CZL_882
30.08.2025: Added the Desktop App for easy calibration → Github
09.09.2025: After flashing the Arduino, make sure to Reset the EEPROM once to make sure the initial config is loaded
09.09.2025: The standard HX711 has a only a 10Hz refresh Rate, you can increase it to 80Hz with pulling the Rate Pin to VCC → See Datasheet HX711
Arduino
- Arduino code is in the src folder

Materials & Print Settings
- **PLA (Standard):** For less stressed parts
- **PLA+ (Sunlu):** For highly stressed components
- **TPU (Shore 95A):** For elastomers
- Recommendation: 15% infill, 2 walls
- **Print settings (all PLA/PLA+ parts):**
- 4 walls
- 20% infill
Base Plate
- Material: **12 mm plywood**
- Dimensions: **400 x 400 mm**
- Equipped with **TPU feet** for better grip and vibration damping
Hardware
All necessary standard parts are readily available (hardware store or online retail):
- **Screws & Nuts:** M3, M4, M5 (various lengths)
- **Washers:** M3, M4, M5
- **Springs:** Tension and compression springs suitable for pedal mechanics
- **Plain bearings/bushings:** 8 mm (for smooth pedal movement)
- **Axles/Rods:** 8 mm steel or threaded rods
- **Wood screws:** for attaching the pedal unit to the base plate
