Developing form

These are my first proper sketches at developing the form of the device.

The form must include:

1. a dial
2. at least 1 toggle switch
3. flat back edge where the solenoids will be
4. must look good either on wall or on flat surface

I am also experimenting with the idea of using aluminum and cork. Both these materials are light weight, relatively easy to shape and cork is an excellent shock absorber.
