Basic Lacing Cross Easter Craft. Use with yarn. There are plenty of plastic needle STL files that make it easier, or just wrap the tips of the yarn in tape.
Couldn't find a similar model on any of the major STL repositories so made my own by remixing Couchjockey's Threadboard.
The author remixed this model.
Took the basic thread board and cut it, adjust size, remixed the parts so that it suited my needs
