I wanted to make stackable, scalable Lego bricks to print between 4x and 16x. I found this model which was pretty close to what I wanted, but I cleaned it up a bit, booleaned the lettering and added some slight bevels.

I also added four flats on the inside to control clutch, the same way an actual Lego stud works. I plan on doing a few different bricks to make human-scale props.
