For info: I do not sell ANY PEDALS OR PRINTED PARTS. That would be trading, and I am not, and do not wish to be a trader. No need to ask. However, I am looking for a company that could produce plastic parts for those who do not own 3D printers. If you know of any…


The SRT GT accelerator pedal is a simple and compact pedal. Designed to be economical, it offers all the necessary settings to achieve the perfect driving position.


Angle can vary from -20° to 35° The starting position is tuned by a screw and a knob (no tool needed).
The end position is tuned by steps.

It measures 195mm from the axle to the top. You can add 55mm with this extension.

There is a preload for the metal torsion spring.

  1. 1 potentiometer 10k (axle diameter 6mm, axle length 10mm)
  2. Cables 3cores 22awg (outer diameter is 4mm).


  1. 1 torsion spring
  2. 0.3 kg PLA (Amazon)
  3. 2 bearings KP001 12mm (Amazon, Aliexpress, Ebay) (Each SRT pedal requires two 12mm KP001)


– 2 x M4x20mm Flat Head Countersunk and 2x m4 nuts (for the pedal plates, you can use 1 or 2 screws per plate… One is enough, but you can use two to be sure). This Amazon kit contains the two screws and many others that will be useful for other projects.

– 1 x M12x100 metal axle (Amazon, Aliexpress, Ebay)


To be added soon.

I've been passionate about cars since I was a kid! I learned the multiple variations of the Skyline R34 through the Gran Tursimo series, until I discovered GTR2 at the wheel of a keyboard. A few years later, I plunged back into Sim Racing with a G27 which made me enter the DIY world. Always looking for an immersion out of reach in reality, I develop projects that I take care to make accessible to any 3D printer owner!

One thought on “SRT Accelerator pedal GT

  1. for those folks US side of things, the proper torsion spring is a bit tricky to find without waiting for several months for the aliexpress shipments. I found a spring on amazon that work, but you will have to cut it down to size.

    the other option that i had decent success with was making my own spring using a spoke from my kids old bikes, 24″ rim minimum. Take the spoke and wrap it around the 12mm rod 2x-3x tightly. works like a charm.
