The DIY LEGO kit provides a low-cost way to create simple machines from LEGO-like blocks. This open-source kit provides a set of unique blocks that are not found in traditional LEGO kits and costs only $2.20 to produce. 


The NSF grant-funded DIY LEGO kit emerged from a collaboration between the TLTL and the CCL of Northwestern University ( The kit is an important part of the project designed to develop hands on science lessons to teach students about the particulate nature of matter. As part of this project, students built four simple machines using traditional LEGO kits. The cost of the kits was prohibitive at scale, so we deisgned a low-cost alternative that could be built using materials and tools found in a fablab.


A standard iterative design approach was employed in the development of these kits.
