Hehe, no unfortunatley I think it went into the bin with the off cuts of the acrylic
But, do like I did and use a piece of cardboard, start it off the same size as the A3 sheet of acrylic and then cut it down and shape it to suit the size you will need, then use a marker pen to trace the shape onto your acrylic and cut to size. Drill holes in the corners of the sheet for putting jubilee clips, cable ties etc through to hold on the spark plug cover and hey presto.
