Lego Brio train wheel set

thingiverse

This is a converter wheelbase that makes you build Lego trains and drive them on your Brio/Ikea tracks. It consists of a base, wheels, and a center that can tilt in the base, allowing the train to drive over bridges. On the center, I have glued on a Lego turntable. You can obtain the turntables directly from Lego at https://shop.lego.com/da-DK/Pick-a-Brick by searching for "turn plate". Alternatively, you can use a site like BrickOwl at https://www.brickowl.com/catalog/lego-turntable-2-x-2-with-medium-stone-gray-top-74340. Finding the right magnet can be challenging. I used a Ø13x3,9xØ3,5mm ferrite ring magnet that works very well. This magnet is available at https://larko.dk/ferrit-ring-magnet. If you find any other magnets that work, please post them in the comments. I mounted the magnet with an 11mm round headed nail, allowing the trains to turn without disconnecting each other. You can obtain these nails at https://www.stofogstil.dk/hobby/moebelpolstring/polstersoem-11mm-oxid-30stk?search=49060. I cut the head off a 1,4mm nail to mount the center and used some 2mm nails to mount the wheels. I had these laying around, so no links are provided for them.
