\section{Dataset}
\label{app:data}
The \dataset comprises a total of 350 data entries, covering various types of origami. We have categorized these based on the required number of folding steps into Easy (3-9 steps), Medium (10-19 steps), and Hard (20-30 steps). Tables \ref{tab:easy_origami_models_2col}, \ref{tab:medium_origami_models_2col}, and \ref{tab:difficult_origami_models_2col} respectively display all the data for these three difficulty levels, including the origami design name, its category, and the number of folding steps required.
All our data are public data or authorized by the original websites and data sources, with no potential infringement risks.
