Hex Quest Interlocking Tile Grid

If you want a version that works, check out Derare's remix here: https://www.thingiverse.com/thing:4076694. This is a work in progress remix of the "Hey That's my Fish" hex grid for use with my D&D style world map tile system, available at https://www.thingiverse.com/thing:3728353. I scaled it down, added a rim/seat/gallery to both the interior and exterior of the tiles, and made the walls slightly taller. It snaps together nicely, but I'm not thrilled with some of the slop in the hexes formed by the grids coming together, so I'll refine that later. Feel free to improve this grid or come up with other ways to hold or wrangle these tiles; I'm not very skilled at precision modeling (I'm classically trained in ceramics). One great idea is to glue sheet magnet pieces to the back of the tiles and use them with a whiteboard or other magnetic surface. You can map your world on a fridge!
