Tildagon Hexpansion FreeCAD templates and NFC

I wanted there to be a template for Tildagon Hexpansions done in FreeCAD and then added a couple of simple variants, one is a simple hexpansion with some M3 holes for adding “stuff”. The other is a model that has a void in it (when printed with zero infill) so you can insert an 18mm re writeable NFC tag in during a pause in printing. I'm printing up a stack to give away/trade at EMF camp 2024.
