When playing Dungeons and Dragons (or another tabletop), you can build your terrain and maps using dungeons tiles.Dungeon/map tiles are tiles with a 1 inch (2,5 cm) grid, making it possible to calculate how far you can walk or if your spell can hit a target (fireball anyone?).To be clear: this is not mandatory. There are dungeons masters using only their words, some people use a big sheet of paper, some use a printed map, some a TV screen, some a combination. Problem: Shifting tilesThe first big map we build was a quest to find a big magical ritual site. We had to enter caves and encountered two basilisks we needed to fight off. We printed and painted for days to make this epicness:My husband made the map in advance and placed in on 2 giant foam boards, making it possible to carry it onto the table when we entered the cave. This picture is about half of the map we had - I'm the bear! 🐻 But when moving the map on the table or when we were moving miniatures around, the tiles shifted and this was quite tedious.So after this experience, we looked into different dungeon tile options to fix this issue for the future. Solution: OpenLOCKAfter some research we decided to go for the OpenLOCK tilesystem.It is a tilesystem that you can click together using 3D printed pins that you can pull apart and reuse every time.This makes it possible to prebuild houses and maps, take them apart and rebuild them all over again.The following 2 maps have been build with the exact same tiles:The back of the map looks like this:Because most of the tiles are about the same height (the sewer tiles are an exception), you can start with a town center, go into an inn, go down a cave, encounter some lava, enter a dungeon, and come out in a graveyard, and so on. SupportlessThe OpenLock base itself is supportless. But you need to remove the little build in support pins.This part is a bit tedious, but we do it while watching TV and when we do it together it goes pretty fast! If the full design is supportless, depends on what you put on the tile ofcourse. When you have something non-supportless on it, you’ll need to build in a support block into your print profile or the bottom part gets tiny not-needed supports. Commercial licenceBecause I genuinely see the advantage of the OpenLOCK system. I contacted OpenLOCK to get the commercial rights.However, some OpenLOCK tiles I uploaded are remixes of existing designs and therefor not allowed commercially. I will make a Google Doc and put a list in our biography to make this clear. So far the following sets have been made or remixed with the OpenLOCK System by us:Garden/hedge grass setTempleCave/Cavern setDungeon stone setRuined dungeons stoneNecropolisDesertVolcanic cavern with lavaGraveyard set SewersCobble stoneCut stoneWoodOther optionsAre there other options to print dungeon tiles that stay together? Of course! For example: Dungeon blocks: a system where your tiles are blocks and you put them into a grid.Magnets: magnets inbedded in the tiles that you link together using the magnetic force. On to many more adventures! Together 3D P.s.: I tried to film a small video of putting a room together.
