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.
Interested in getting in touch and showing your experiments? Join Kristoffer on the Arduino forum dedicated to Materia 101 and give us your feedback.
