However, the pre-built models or pieces limited your imagination. The Lego and other kits did not let you make custom pieces. You were building the Death Star or an X-wing.

Combining model kit parts is known as kit-bashing. Lego has made it difficult. Decades ago there were the range of standard Lego pieces. Lego made it easier to make a real-looking Death Star model but they made it harder or vastly more expensive to customize.

Snapships makes it easier to use software to model and design what you want for a model spaceship. You start off with their designs and then you are freer to work out changes and customization. Snapships pieces are made to 20-micron precision. This is the level of Lego precision but without forcing you to buy the next $50-1000 kit for special pieces.
