High-Performance DIY Sim Racing Pedals

Take your sim racing setup to the next level with these custom-built, 3D-printed pedals designed for precision, realism, and durability. Perfect for PC-based racing simulators, these pedals are engineered to give you the feel of real racing hardware—without breaking the bank.

🔧 Features:

• Fully 3D printable design
• Compact form factor for small sim rigs
• Designed to work with a rotational potentiometer
• Spring-loaded for return force – can be adjusted or swapped
• Strong mechanical construction for a stable brake feel

🛠️ Requirements:

• Potentiometer (rotational)
• Compression spring for brake pedal (lenght: 3.2cm / width: 2.3cm)
• Compression spring for gas pedal(desired spring with a lenght of 5-6cm)
• M3 bolt and nut
• M5 bolt and nut
• M4 bolt and nut
• Bearing for gas and brake pedal (8x22x7)
• Bearing for gas pedal (4x13x5)
• metal rod 2x (width: 6mm)

🖨️ Print Settings:
