This week we are presenting you a new tutorial on 3d printing of Lego-compatible pieces with Materia 101. Kristoffer designed a brick with the parametric 3d modeler FreeCAD that can hold a small servo. Following the 10-step instructions  you can easily add wheels to robots built in LEGO and  use specific servos with different sizes.
