Ford Flathead V8 Engine - Moving Model

Designed by: ericthepoolboy
Hardware Kit and Build Support by MakerRx

Before overhead valves took over, there was the Flathead V8 - raw, simple, and legendary. This 3D printable scale model brings that piece of history to life with moving pistons, cam-driven valves, and a crankshaft.

Originally modeled by ericthepoolboy. We teamed up with Eric to put together a hardware kit for anyone who wants to skip the parts hunt and go straight to the fun of building.

⚙ Key Features:

  • Accurate recreation of the Ford Flathead V8
  • Working mechanical motion powered by a geared DC motor
  • Great for classrooms, garages, and display.

📦 What's Included in the Files:

  • Complete STL file set for the Flathead V8 
  • Build Instructions.

🔧 What You’ll Need:

  • FDM 3D printer
  • Basic hand tools
  • Super glue and soldering tools
  • Optional but recommended Maker Rx hardware kit

🛠 Official Hardware Kit:

To simplify the build process, Maker Rx collaborated to create an official hardware kit. It includes bearings, belts, fasteners, rods, magnets, a DC motor, and more. Everything you need besides the printed parts.

🧪 More Maker Rx Kits:

This model is part of the Maker Rx engine series. Explore our supported kits including the EJ20 Boxer, LS3 V8, and more. All include free downloads, hardware kits, and instructions.
