(): move the object 1 unit in the X direction, 1 unit in the Y direction, and -1 in the Z direction (i.e. Translate: this tells OpenSCAD to translate whatever follows, the cube in this case. Translate really just means we are going to move the cube.Īdd a translate just before the second cube line: This cube is not centered on the first one so the next step is to translate it so that it is. We are now going to use a second cube to cut a hole in the middle of this one.Īdd the following line so your script looks like this:Ĭompile (F5) and you should see a new cube. A cube shape should appear in the object area. Compile the cubeĬompile the cube by selecting the Design menu at the top of the screen and selecting Compile. OpenSCAD uses generic units for dimensions but in our model they will become millimeters so you can think of the cube as being 8mm x 8mm x 4mm. Our cube will be 8 units in the X and Y direction and 4 units high. cube(6) all of the sides would be the same length. (): dimensions for the sides in the X, Y and Z directions respectively. In this case X and Y are horizontal axes, Z is vertical. If a single number was used here, e.g. We could set up for individual walls but in this case we are going to make them out of a single cube. There are a number of standard views of the object that can be used by using the following shortcut keys or from the View menu at the top of the screen.

OpenSCAD has a very simple interface that includes an area for writing script (on the left), an area where the rendered 3D object will appear (on the right), and an area for progress, errors and general notifications while rendering an object. It can be a little tricky to get used to but it allows for accuracy and creates solid objects both of which are very important in 3D printing. Instead of interacting directly with the 3D model you write script that OpenSCAD uses to create objects. OpenSCAD is a 3D modelling tool that is ideal for creating objects for 3D printing. Feel free to increase the values or scale up before 3D printing. The dimensions used throughout this tutorial are very small (less that 1cm in most cases) so the resulting model is small. We are going to create this simple castle with four main walls, four towers and a door. ![]() This resource works through some common techniques using the 3D modelling application OpenSCAD to create a simple model suitable for 3D printing.
