Its a piece of perspex basically, it was alot of effort without knowing where to go for materials etc
You need atleast 4.5mm perspex, and i just mounted it as a flat piece, but you can see the edges of the reflector so i had to paint a ring around the outside to hide them (pretty difficult to mask a perfect ring around it when its a slightly oval shape )
But it was all worth the effort, and i like to have soething unique
