This set is three hexes that join together to make one large rock pile. All my hexes are designed to use 4x6mm round magnets, they just push into the holes.
This set is designed with my new V2 Tiles, these have a keyway that allows a 3d printed "key" to be used to help lock the tiles together.
I also include a Blank Hex that has the key, it can be split from the stl to just print the keys.
These are 240mm wide at the widest point, they can be scaled to whatever size your printer is and should not cause issues.
Each hex is flat with rocks as part of the print. Fully compatible with all my Hex tile sets. There are a few overhanging rocks so some configurations may not be possible.
