This time we build a stamp with the open source software FreeCAD and manufacture it in the 3D printer with the appropriate elastic material.

FreeCAD is free, open source software for creating three-dimensional models. In the make article “Ring free for FreeCAD”, we have already shown how to use FreeCAD to design a finger ring with embossed and attached lettering and have it manufactured by the service provider using metal 3D printing. The FreeCAD drawing tools were only briefly discussed, which is why this time a stamp is constructed with the help of an image template and also 3D printed. The stamp plate is made of flexible, rubber-like material, while the handle is made of solid plastic.

You can download FreeCAD (Download) for the Microsoft Windows, macOS and Linux operating systems. After you have installed the program, start a new document via the Dashboard . First save it under File / Save under the name “Makey”, because in this example the contours of the Maker-Faire mascot, the robot Makey.

On the left side of the program there is a tree view in which the document structure is shown. As soon as you create a new object, it is there again. If you click on it, the properties window opens below the tree view, in which the parameters of the object can be adjusted.
