A laser cut replica of the Union (Federal) Cipher Disk.
The SVG file consists of several layers that can be combined in different ways
depending on the material to be cut.
For acrylic the layers
can be used to get a larger disc with a circular pocket in which the smaller
disc can rotate freely without the need for additional fixation.
For wood the layers
result in a back plate, an outer ring and an inner disc.
The ring get glued to the back plate. The inner disc can then move freely
inside the ring.
For paper and cardboard the layers
lead to two discs with concentric holes that can be mounted together
with a clip or pin.
This also works well for most other materials if a screw is used to
mount the discs together.
See also my Confederate Cipher Disk and Alberti Cipher Disk for
more example images of how the finished discs look.
