Expand your Duplo train sets with these multicolor action bricks!

Model Overview & Print Notes

This set contains all the Duplo compatible action bricks you need to expand your train sets. The bricks are multicolor optimized, so you can print them to look like the original bricks. The set includes the following bricks: Stop Refuel Light Horn Direction Blank The bricks are designed to be Duplo compatible, so they can be used with any Duplo train set. They are also easy to print, and no supports are required. If you use the stl-fiels make sure to split them into parts. I recommend using PLA filament for best results. I have used Aurapol L-EGO colors ( Yellow , Blue , Green , Red ) for the models and had no problems with the brick recognition.
