Infinity Trax - Farraday Edition | Modular Magnetic Marble Run |

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 versions of this track for Will Smith(!), have had it installed in museums around the world, and HQ's of fortune 500 companies. It has also being used by many educational establishments and has been featured at Cheltenham science festival. In short, it's been thoroughly tested and geek approved.

This is the 'Farraday Edition' which means it includes all the trick and track sections, as well as the Achimedes screw lift mechanism as well!

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:

• Archimedes screw Lift
• Archimedes screw lift extension
• 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
• Orbit return
• 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. The cost for the materials for one Archimedes screw lift is around $25 if you buy on Amazon, or around $12 on aliexpress.

n.b. You will also need to use a soldering iron to be able to make the Archimedes screw lift.

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