3D printed discs

Here in the modern age, fans of the Elna Supermatic line have started designing their own pattern discs in cad software. Quite a few discs are now available as 3-d printed models.

• Here is one source for not only a few 3d printed discs, but the software to generate your own. (You'll need to learn to use the OpenSCAD modelling program to use the software, but it's not all that hard if you're already a programmer.) https://github.com/ln-komandur/elna-cam-discs
