Creating Custom Models

To create your own custom signs, you'll need OpenSCAD.

Model Parameters

From the GUI, open the text.scad file in OpenSCAD. You can modify all parameters in the right sidebar of the OpenSCAD window. The parameters you can modify are:   

• lines: An array with each line of text you want to use for the sign. Default value is ["it works", "on my", "machine"].
• font: The font used for the sign. The default value is Liberation Sans:Bold.
• font_size: The approximate font size for the sign. Default value is 10.
• base_thickness: The thickness of base. Default value is 1.
• font_factor: A factor to calculate the font width size, used to centralize the text in the base. Default value is 0.90, which is a good value for most fonts. You can modify this value to adjust the base width.
• base_padding: The padding between the text and the base. Default value is 10.
• angle: The angle of the text. Default value is 45. Please note that for support-free printing, the angle should not pass 60 degrees.

After you're satisfied with the model, first render it by pressing F6, than you can export it as an STL file by clicking on File-> Export -> Export as STL… in the OpenSCAD GUI.

Print Advice

I printed my own signs using the following settings:

• PLA filament, 0.20mm (speed)
• No brim, no supports
• 10% infill

One nice idea is to make filament changes so that the text faces have different colors.
