In my previous post, I walked through the process of creating detailed textured gaming tiles that are compatible with the OpenLOCK™ system from Printable Scenery. They also work with DRAGONBITE™ from Fat Dragon Games (or any other 3D printed tile system).
That post demonstrated how to generate crisp sci-fi wall "panels" and some pipes or hoses.
In this post, I will demonstrate a method for creating a stone texture for use with a dungeon tile.
You can download the STL for this tile from Thingiverse.
First, create a new image in GIMP that is 50.8mm wide by 43.01mm tall. Fill the background with black and then create a new layer.
On the new layer, choose the lasso selection tool and draw some round, stone shaped ovals with it. Hold the shift key down when you want to add a new oval. When you've drawn the oval, hit the
Enter key to complete it.
Here is an example:
At this point, what I normally do is create a new layer to hold the stone template before I make any further changes. Once I've created the layer, I choose white from the color picker and then choose the paint bucket (
Shift+B). Fill the selected area with white and then hide the layer.
We can then use this as a selection later on if we make a mistake and need to get back to the original shapes.
Now, from the menu, choose
Select -> Feather. Type in 25 pixels and click OK.
Now, select the paint bucket by clicking the button on the tool menu or hitting
Shift+B on your keyboard. Choose pure white from the color selector. Then click inside of one of the selection areas to fill them all with white. Because the selection is feathered, you will see a gradient effect on the edges. This is what is going to give our stones a 3-dimensional texture.
Export the image as a png. Open the Lithophane Generator and pick the exported image. Change the settings so that they match the following:
Once you have set the settings, click the
Model button. You may have to hit the
Refresh button to get the changes to take effect.
Download the STL to your computer for use in the next steps.
Next, we need to load Tinkercad and import the OpenLOCK A-Wall template. Once that is done, we need to load the stone texture STL that we just saved from the Lithophane application. Be patient, this will take a long time to import since it is so complex.
After it has been imported, rotate it and position it on the A-Wall template. Then copy and paste it and flip it. Reposition the copy so that it is aligned with the backside of the wall.
Select all three objects and Group them together (this will take a very long time).
Once that is done, export the STL and open it in your slicer. I am using Cura.
I changed my wall line count from 2 to 3 for this print to give the stones a little more strength.
Analyze the layers to make sure you don't have any overhangs and start printing.
Here it is as printed by my Ender 3 Pro at 60° bed and 200° hotend temperature.
