Custom LEGO Block

The LEGO Block project was for my Advanced Engineering and CAD class in high-school. We were tasked with reverse engineering a LEGO block and creating our own custom design. This page will showcase the process I took to make the pieces.

Initial Sketches

The first part of the project was to create a board drawing of a 4 x 2 Lego block. The pictures here showcase my initial sketches I took before moving onto the final board drawing. I took measurements using calipers to get all the information I needed.

Board Drawing

My finalized board drawing is shown below. A hand drawing was only created for the 4 x 2 block.

Creating a CAD Model

After taking the measurements with the calipers, and creating the board drawing, I made a CAD model of the block in Solidworks and created a digital drawing. Note that I used metric units for this drawing instead of ANSI as I determined that the actual part was likely modeled using this unit of measure. This block was 3D printed and was able to snap together with actual Lego blocks.

Creating My Own Lego Block

The below drawing showcases my new, custom Lego block design. I chose a pyramid-like design with a corner cut out. This block was also 3D printed, and when tested against Lego blocks made by the company itself, was found to snap together nicely. 

Reflection

The reverse engineering 4 x 2 Lego block and the custom block were able to be successfully printed and snapped into blocks made by Lego. This project helped sharpen my drafting skills - both digital and by hand.
