Spiky Torch Column
A dungeon terrain column for housing an LED tealight. Measured to fit the "Room Essentials" brand LED tealights sold at Target.
Design inspired by the architecture in the game Ico by Fumito Ueda. Octagonal shape makes it easy to use either along the walls of a dungeon hallway or as corner pillars in a room. I originally made this to go with Ultimate Dungeon Terrain. 4 columns and a couple doors to suggest the shape of the room -- no need for walls!
You may want minimal support under the torch, but you should be able to print the entire model without supports with only a minor loss of details.
At a minimum, you will need an LED tealight. This was designed for the "Room Essentials" -brand tealights sold at Target. Other brands may or may not fit.
Highly recommended is to also have some narrow speaker cable.
First, you will need to disassemble your tealight. Remove the battery. Then you can usually wedge a narrow screwdriver under the cover of the tealight to remove it. You will also want to remove the "flame" from the tealight -- you will need it later.
You can simply insert the innards of the tealight into the torch column as-is. You will get a very dim light.
For a stronger light, cut a 1.25" length of speaker cable. Carefully clip the LED off of the base at the midpoint of its connector. You want to ensure you still have some lengths of bare metal on both the base and the LED.
Next, you can either solder the LED to one end of the speaker cable and the other end to the base. Or if you're like me and don't have access to a soldering iron, you can simply push the metal pins of the LED inside the speaker cable, then push the other end of the cable onto the metal pins on the base of the tealight. (This is the reason for suggesting speaker cable, as the loose collection of wires inside the insulation makes it relatively easy to push the metal pin in.) Secure with glue.
Now, push the joined tealight base, speaker cable, and LED into the bottom of the column, ensuring that the LED travels into the hole inside the column and exits at the torch. The base of the tealight should click into place on the bottom of the column.
Finally you can insert the "flame" piece from the tealight into the torch and secure with glue. I usually cut about 0.5" off of the bottom of the "flame" so that it doesn't stick up too high from the torch. When inserting, ensure that the LED ends up inside of the "flame".
Reinsert the battery, flip the switch on, and enjoy.
