Tablet weaving cards, with several hole configurations based on those found in the 9th century Oseberg ship burial (located near Tønsberg, in Vestfold county, Norway).

The OpenSCAD file allows you to customize the size of the tablets, the size of the holes, the thickness of the cards, and how rounded the corners of the cards are (and a few other little details).

This is a work in progress; I'm planning on doing more testing and also updating the code to work with the Thingiverse Customizer. In the meantime, you have to use OpenSCAD to customize. Or comment and ask for a different size.

Let me know if you have any questions or suggestions for improvements!
