Miniscape Tiles
cults3d
Heroscape, but mini. These tiles were designed to imitate the interlocking and stacking features of Heroscape terrain tiles, but be scaled for 1-inch D&D miniatures, and be easier to 3d print. The tiles are designed for 1-inch D&D miniatures, but are actually larger than 1-inch hex tiles themselves, so I would recommend printing out enough of the larger tiles to make a battle map, so that you have something to build off of. The tolerances of the dove-tail joints should be fairly generous, but you can fiddle with (in Cura) the Horizontal Expansion and Initial Layer Horizontal Expansion settings to get them to fit together as you would like. I print the tiles upside-down to reduce the amount of support material necessary. At the time of publishing this, the Heroscape patent has expired, so there should be no legal issues.
