Lego Brick Sand Mold

This little mold can turn any sand into LEGO bricks! And although they are made of sand, they still interlock very well!

If you have ever wanted to build Lego at the beach, then this is the perfect model for you! 

To make the bricks you simply just press in some sand in the mold, and then press the bottom plate against the bottom to make the bottom holes. But if you are building the base for your build, the holes in the bottom are unnecessary. 

The bricks created by the mold is in the size of a DUPLO brick, so if you wanted you could mix DUPLO with your sand Lego. And believe it or not, but they actually interlock with each other really well!

You don't need any special settings or support, and it doesn't make any difference if you print at a larger layer height. I printed mine at 0.28 mm, just under an hour. No supports needed if you print them as the model orientation already is.

The possibilities of what you can do are endless, but whatever you build I'm happy to see what you have done in a make!
