20mm electrical conduit construction corner

A corner piece which makes constructing a cheap enclosure from 20mm electrical conduit easier.
Has a flat base for better stability and durability as a 'foot, and to make it easier to fix a roof to the enclosure.
I used heavy duty clear book-wrapping plastic for the sides of the enclosure, secured with clothes pegs, and with segments of conduit sliced open and softened with heat to form clips.
