Made for My Grandpa

This tool was created for my grandfather who loves 3D printing but struggles with complex modeling software. He doesn't speak English, which makes most 3D design tools inaccessible to him.

Despite these challenges, he's passionate about creating 3D prints for our family. He uses his BambuLab A1 printer and now can easily create custom models by simply describing what he wants.
