Magnetic dungeon STL 3D Files 28mm

Recommended Posts


STL files for 3D printing a modular dungeon system for RPG games.
Create your own versatile dungeon for 28 to 32 mm miniatures.
The wall sections have slots for D3x3 mini magnets so they stay firmly on any metal surface. Doors and chests do not have slots for magnets but magnetic tape works fine.

Prices in Swedish but 10 Swedish is basically one EUR an I use this rate in the text. Actual rates may vary.

I started designing these for when playing role-playing games. I wanted something to represent walls but did not want to print a large base or floor. Floor means more to print and you need many different types to make different size rooms. More to print and hard to find all pieces when gaming.

So how to make walls stand by themselves? Well I had mini magnets for my minnies and decided to use them in the walls. For a base you can use a metal sheet that you paint/glue paper on or maybe a magnetic whiteboard? Then you can attach printed paper for different floors or use as is and do notes.

There will be STL files for, straight walls, corners, bends, doors, a stair and chests. See the pictures for what is included in the different pledge levels.

Walls have a height of 40 mm and a depth of 10 mm. Lengths vary from 30 mm to 120 mm. Doors are 30 mm wide and 45 mm high.

The minnis shown in the pictures are from various games and are only there for scale reference. Other 3D print models are from thingsverse.

I only will provide the STL files for download. Other components you have to source yourself.

Print quality depends on your printer. Samples in pictures printed using my da Vinci miniMaker from XYZ.

      "You take your game seriously. Now it's time for a serious screen.
      In October of 2018, Dog Might released the first fully sculpted GM Screen, the Valhalla Screen. Since then, we have released over 30 more designs, including officially licensed screens for: Pathfinder, Call of Cthulhu, and Vampire: The Masquerade. We have also designed screens for you favorite shows, such as Relics and Rarities and the Critical Role stream of Undeadwood. Over the last year and a half, our Valhalla Screens have proven to be our most sought after product. "
      ... Would it surprise anybody here to know I want one? 
      If I can't have one, at least I can spread the word. ;p

      Lots of 3d printable animals. While Thingiverse has quite a few, this ones are rather nice looking.

      This came up after I pledged for the new EC3D campaign. It looks interesting thou I'm not sure how comfortable it is or since when I use a dropper bottle, I use the standard Vallejo-Reaper-Army Painter-whoever bottle style. Squeezing the body vs the tip. Granted you can't squeeze GW bottles. I may or may not back this one just for curiosity sake.

      If you like scifi, this looks like a good one and reasonably priced too.

      This looks quite nice:
      The Shipping container as packaging is a nice touch.
