The Electric Marble Lift V4a is a brilliant 3D printing project that combines fun and technology in an elegant way. I’ve printed this lift twice already – and each time it was a highlight when playing with my daughter and our GraviTrax track. If you’re looking for a functional, fun, and visually appealing upgrade for your marble run system, this model is a must-see.
What is the Electric Marble Lift V4a?
The Electric Marble Lift V4a is a motorized marble elevator that integrates perfectly into marble runs like GraviTrax or similar systems. The model was created by Makerworld user Zabé and features a compact, functional design that is easy to print and assemble.
The V4a version is a simplified and optimized upgrade of earlier lift designs. Using a small DC gear motor (e.g. 3–6V), marbles are reliably transported upward – perfect for endless playtime.

Here’s a photo of the lift in action as a great addition to the GraviTrax track. You can also see the power bank, which powers the lift for over 8 hours thanks to its low energy consumption and pleasantly quiet motor.

My printing experience and tips
I printed the lift with my Bambu Lab X1 Carbon (link), and the model came out very cleanly without the need for supports. The part accuracy is excellent – kudos to the designer!
👉 My recommendations:
- Material: PLA (PETG optional for more durability)
- Layer height: 0.2 mm
- Infill: 15–20%
- Print time: approx. 6–8 hours depending on settings
Assembly is straightforward but requires a bit of precision when inserting the motor and moving parts. Once up and running, the lift becomes a real eye-catcher – for kids and adults alike.
Here you can see the worm gear right after it was printed on my 3D printer:

We started at home with this starter set, and over time, added more. The marble run fascinates not just the kids – we parents also enjoy building creative tracks, and the motorized lift is a fantastic enhancement.

Why this marble lift is so exciting
For my daughter and me, this lift is more than just a tech toy: it brings movement and dynamics into play and greatly expands the possibilities for track layouts. Especially when combined with GraviTrax, it sparks new creative challenges and ideas.
The lift also impresses technically: the motor, reliable mechanics, and high compatibility make it a great project for both makers and families.
