IMPORTANT NOTE: Due to file size restrictions on MyMiniFactory, this tileset has been broken up into two parts. This is part 2 of the tileset. It contains 63 tiles. The product description below, and the image gallery, describes both parts. You will need to purchase both parts to get a complete tileset.

Part 1 is available here:

Intended for 3d print.

What is this?

Drakborgen, known as Dungeonquest in the UK, is a boardgame originally published by Swedish game company Alga in 1985. It is considered a classic in Sweden, and unfortunately less so in the UK/US - possibly because the English version lacked a lot of polish and original artwork.
In the game, you explore the interior of a sinister fortress, hunting for the dragon's treasure hoard hidden somewhere within the treacherous maze.
As you play, you continuously map the fortress using flat cardboard tiles. This product is an attempt to create a comprehensive 3D tileset , allowing you to explore the dragon's fortress using three-dimensional tiles instead of flat cardboard. The 3D tileset contains the exact same number and type of tiles found in the original 1985 edition, so you can swap out the cardboard tiles for the 3D set without it affecting gameplay. The 3D tiles are compatible with the original Drakborgen game board (see image gallery), and, to my knowledge, with Dungeonquest as well. They can also be used as interiors for other boardgames or tabletop games, like Warhammer or Dungeons & Dragons.
The tileset contains 126 unique tiles in total, including four tower tiles that can be used as the starting points for the game.
The artstyle of the 3D tiles are inspired by the artwork of the original game. This includes a forced perspective visual style, where the walls and objects of the tiles slope inwards at the bottom to give the impression of greater depth when viewed from above.

Will I still need the original game to play using these 3D tiles?

Yes, definitely. This product only includes models intended to replace the cardboard tiles of the original game. You still need the rulebook, cards, various game pieces et cetera of the boardgame in order to play.
If you do not own any editions of Drakborgen or Dungeonquest already, there are plenty or copies for sale on various online auction sites like eBay. Swedish game company Fandrake also recently re-released Drakborgen, and is considering releasing a true English version in the future. As of May 2022, you can petition them here:

How do I use this tileset?

First off, you'll need access to a 3D printer.
Secondly, you need to print 1 copy of each tile in the tileset. If you intend to use the 3D tiles for the original Drakborgen board game, you need to print 116 of the 126 tiles (the remaining 10 are extra tiles, plus the four starting point tiles that are entirely optional).
The tile print files are numbered, so keeping track of which tile you need to print next is easy. Once you've printed the tile marked no 1, you print no 2 and so on. The "bonus" tiles mentioned earlier are clearly named 'extra' , so you'll know you can skip them.

Do note that 116 tiles are quite a lot of models to print - If you intend to print up an entire set, expect to devote a lot of printing time and filament/resin to the project. A single tile printed at high settings takes approximately 1.5 hours to print. Also note that depending on the quality of your printer, some of the finer details on the tiles may or may not show up properly at default scale.

Each tile is currently prescaled to 4.5 cm x 4.5 cm in size. The dimensions of the original cardboard tiles vary by edition, but it is my understanding 4.5x4.5 are the dimensions used in the original 1985 release. If you own a Drakborgen/Dungeonquest game board, always check what size is right for you , and adjust accordingly before printing.

Finally, note that most tiles will have a round symbol display added to one edge (see image gallery). This display will feature either an arrow, a triple arrow, a foot stepping on spikes or an eye. These symbols corresponds to the "ordinary room", "corridor", "trap room" or "dark room" found in the Drakborgen board game. In the original game, the type of room is denoted by a dot in a specific colour - in this 3d tileset, symbols are used instead since the printed model will be monochrome.

Will this tileset work for other tabletop games?

Yes, tolerably so. Just be aware that a tile printed at, for example, 28mm scale will take quite a lot of time and material to print. And that the tiles use forced perspective, which may or may not be to your liking.

Note that the number of tiles included in this tileset is supposed to correspond to the number of carboard tiles in the the original 1985 Drakborgen edition only. Later editions have expanded rules, and consequently more tiles as well. If you want me to add additional tiles to make the tileset compatible with later editions I may be able to do so, but you will probably have to provide me with a comprehensive list of the number and type of tiles required for Your particular edition.
