Duplo straight train track rails.

cults3d

I've created a 100% compatible Duplo train rail system that can be printed with a 3D printer, making expensive gray tracks a thing of the past. Now you can even print pink rails if that's your style. Currently, I'm working on designing bended rails to add some extra realism to your prints. If you're excited about this project and decide to print one for yourself, please share a picture with me - I love seeing things I've designed being used by others.
