I've started to model LEGO® like blocks since I wanted to have the possibility to model new parts. First of all the problem with 3D printed legos are the tolerances so I've started to change the model dimension to fit real legos. Also I've modified the Lego design to make it printable without support.

For the moment these 3D printed legos works with real legos, but they do not work with each other. Tolerances are very different from 3D print/3D print and 3Dprint/injection moulding.

As I improve the design I will update the models and when I will make new lego part I will upload them too.
