The battery powered Archimedes screw lift means you can create tracks that loop around on themselves. Use in conjunction with the modular 'Archimedes extension' to increase the height of your elevation.

The cost for materials for the Archimedes screw lift section is approx $27 with the Amazon links, and around $12 using the aliexpress links I provide (should you prefer that option). You will also need to use a soldering iron for this track section.

This model is one track section of the Infinity Trax modular magnetic marble run. Check out my store for the complete catalogue or membership deals.

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.

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!

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.
