Description

Electric Marble Lift V4a – Endless Motion, Simplified!

Take your marble runs to the next level with the Electric Marble Lift V4a! This upgraded version makes continuous fun easier than ever by transporting marbles back to the top for uninterrupted action.  

Based on feedback from the community, the V4a is a streamlined upgrade to the original V4 lift. With a reduced number of parts and simplified assembly, this version is faster and easier to build. Now requiring just 10 parts + 12 pins, the V4a ensures that creating your lift is a breeze!  

Key Features: 

  • Simplified Design: The V4a improves on the V4 by reducing complexity and cutting down the number of parts needed.  
  • Motor Compatibility: Supports both N20 and N30 motors, with separate plates for each option.  
  • USB Power Convenience: Power the lift with a USB cable and switch, allowing you to use a power bank or adapter and easily control it with a simple toggle.  
  • Adjustable Exit Heights: Standing 225mm tall, the lift includes multiple exit points spaced every 30mm for maximum flexibility in your marble run designs.  

Whether you’re building from scratch or upgrading an existing setup, the V4a brings effortless automation and endless fun to your marble runs.  

 

Print it, assemble it, and let the marbles roll forever!
