EJ20 Boxer Engine Model - Hardware Kit


Combined with yet another of ericthepoolboy’s designs, this kit will let you get up close and personal with a 35% scale model of the EJ20 Boxer engine.  The model is fully functioning.  All the belts, pistons, and other engine parts move and work just like the real engine.  Keep in mind that this is still plastic after all, meaning no combustion – so don’t go putting fuel in this thing.


This kit is for the true gearheads.  It contains only the non-printed parts required to assemble the 35% scale EJ20 Boxer engine.  To complete the project, you’ll need the plans and files available on the linked Thingiverse page. This kit is also compatible with the newer cutaway design.


Kit includes:

  • Fasteners
  • Magnets
  • Bearings
  • Springs
  • Threaded rods
  • Closed loop timing belt
  • 500 RPM DC Geared Motor
  • Speed Controller
  • Electrical Connections
  • Power supply


Some previous experience printing and assembling ericthepoolboy’s engine designs is recommended prior to printing this design and purchasing this kit.  Buying this kit will directly support the creator and his future endeavors.
