3D printing, at least typical FDM, does not have near the tolerances required to snap onto the real bricks, but I found that the “LEGO technics” side of things (with the pegs and holes) is much more forgiving since the real lego pegs are flexible, they can snap into rigid 3D printed parts once you get the scale right.
Years ago I was teaching a robotics class where I asked the kids to customize their robots’ faces by drawing new parts like mustaches and eyebrows with markers, and then used Inkscape and Tinkercad to model the parts in 3D.

- sokoloff 5y agoIt doesn’t have the tolerances to create bricks that play at all like real Lego, but it’s not that hard to make parts that will snap onto real bricks or to offer studs onto which the real parts can snap. I’ve made many a custom kids’ name tags as parts that can plug into Lego bricks. No one thinks they plug as nicely, but Lego doesn’t have the kids’ names either, so…
- animal531 5y agoThis is a good answer. As a kid there were always ideas that I wanted to build, but I would for example not be able to construct the shape required in the working space that I had. For example pieces like angle switchers, mixing holes for axles with other pieces, parts that allow things to slide etc.
