LEGO FINAL MET-112

The idea for the CAD final was to use pre-existing parts to build "new kits" with instructions and packaging. 

I wanted to make some thing that had moving parts and would have liked making it more complex.... but 3d printing the parts took a considerable amount of effort.  3d printing is not a preferred method for making Lego's in my opinion. 

Working axles and 3d printed wheels was the biggest challenge. I did have to modify the injected molded Lego axle model to a simpler design that could lay flat for printing and better rigidity.  

If you like Legos and haven't tried Studio 2.0 from Bricklink.com  your missing out ... it has some amazing features and is free!  I used it to make the instructions and was blown away by how it simplified that process! The PDF is viewable/scrollable below.

Parametric Lego  Fusion360 file downloads below that you can make any normal plate or  brick Lego by just changing the Rows and columns. The FX  tab in Modify will bring up a table for you to adjust  for 2x4 , 4x4  ect. 32x32  whatever. Height is also adjustable. 

The file works with real Legos reasonably well.
