The crowdfunded german box for Halls of Hegra is slightly larger than the original english box so custom inserts designed for the original are a little loose.
This insert is meant to be combined with Hextras awesome Halls of Hegra insert but should work with other inserts as well: https://www.printables.com/model/559165-halls-of-hegra-insert
I created the topographic piece with https://touchterrain.geol.iastate.edu/, placed a 2mm hole where the Hegra fortress was built and glued a piece of filament in.
The author marked this model as their own original creation.
