Reversible lens hood for Olympus 45mm f/1.8 lens.

My first version was more compact but did not have room for your fingers to remove the lens cap and it could not be reversed. This version can be reversed and even with my thick fingers I can remove the lens cap. Don't mind the ridges you see, they are not in the design but caused by inconsistent abs filament flow. Printed on my Makerbot ToM it is a perfect fit.
