user3237: Not exactly Arduino-specific, but if you want to get a daily usable device (instead of a floating wire connection on your table) you eventually want to put your (Arduino-based) device into a nice casing. What are the different types of cases that people use?
I found soap cases as well as kitchen boxes (used one large cheese box from Mepal Rosti).

user3493: If you have affordable access to a laser cutter, then you could laser cut a box to exactly match your project.
Laser cutters typically come with software that reads SVG or DXF files. 
Find out what file types are used, then search the web for something like "laser cut box design tool SVG", and you'll find a bunch of ways to make the box outline.
For example, this laser cut box web site generates a pdf file, which you can 'print'. You fill in a few parameters, and it does the rest, generating all the profiles for interlocking edges. Even though the edges are interlocking, you might want to add some glue to make it more robust.
An advantage of laser cutting is you can choose the materials. Maybe you'd like wood, with a transparent red acrylic lid. 
A further advantage, if your laser can read things like SVG or DXF, is you could use a CAD or drawing program to modify the box. So, for example, you could 'etch' labels onto a control panel, or cut extra holes to mount LEDs. Or just decorate the outside of the box.

user1566: So far we have used:
ABS cases (pic camdenboss.com):

Small pelicases (convenient to open, pic pelican-case.com):

3D printed cases with a clear perspex window (pic instructables.com):

I've seen other people use laser cut perspex (pic spikenzielabs.com):
