Infinity Trax is a modular magnetic marble run that can be built (and re-built as many times as you want) on ferrous metallic vertical surfaces such as fridges or magnetic whiteboards. It's part puzzle, part STEM toy, part artwork, and a truly unique marble run with more possible track designs than there are atoms in the universe!

I've made a version of this track on live TV for Will Smith; have had it displayed in museums around the world; it was featured at Cheltenham science festival; it's been used by numerous educational establishments; and is due to be installed at the HQ of a huge fortune 500 company. In short, it's been thoroughly tested and geek approved.

This is the 'Newton Edition' which means it includes all 17 trick and track sections for amazing gravity based marble runs.

I make other variations of this track that are available in my store. If you want to build your track bit by bit at a lower cost of entry, or want to make these STLs commercially, then become a member.

Due to the free form nature of track design, it transcends from 'just another marble run' to a mesmerising super-puzzle which provides endless hours of creative problem solving, imaginative play and is the toy that will be the most played with more than any other in the house.

Because making new tracks is easy and intuitive, the limiting factor to marble run glory is imagination and creativity, making it the perfect way to engage those beautiful brain cells. Don't be fooled though, simple is not the same as easy - you'll need to manage marble speed, and plan your run carefully in order to achieve true marble run greatness!

In the 'Farraday' there are 19 unique trick and track sections with over 180 separate STL files. Here's the pieces you'll be able to make:

• The Arm
• Straight 10cm
• Straight 20cm
• Mini Bend
• The Wheel
• The Corner
• The Double Backflip
• The Manual Launcher
• Third Dimension
• The switch
• The switchback
• The orbit

• The Valley
• The Hill
• Zig-Zag
• Third Dimension

Included in the download is a full 16 page set of instructions with links to build guide videos, as well as a detailed read-me section which has tips on best practices for 3D printing your track.

You'll need to buy magnets, as well as some glue and other small items to make your track. I made a shopping list which will be included with your download so you'll be able to easily purchase everything you need to make your marble run. The cost for materials for one track section is around $0.60 if you shop on Amazon, or around £0.25 on Aliexpress.

In order to be able to make this, you will need a 3D printer with a bed size of 20x20x20cm
