Disagree. Most plastics don't fold worth a damn, and can be difficult to
join with "normal" workshop methods.

Thermoplasts (for example perspex, polyethylene, -propylene or -styrene)
can be folded by cutting a grove along the foldline, about 1/3 - 1/2 as
deep as the material is thick and 1 mm wide. Then use a blow drier to
warm the plastic and fold over a table corner or the like.

Note however that plastic does not screen electromagnetic fields.
Sensitive circuits (like preamplifiers) or those working with high
frequencies (anything containing microprocessors) should be in a metal
box, to avoid EMI problems. And of course anything working on mains,
unless you can do double insulation.
