Super bridge building brick compatible with DUPL0, Strictly Bricks, etc. - 2mm thin 2x4 brick

The Lego Duplo train is great, but to build bridges, you need a ton of bricks for supports.

This brick solves this issue, print it and have self-supporting connections between the tracks. Just support it with a toy and you're good to go.

Make sure that the brick has a tight fit, print with some over extrusion if needed. O yeah and you will probably need a lot!

Have fun!
