Olympus 45mm f/1.8 lens hood (similar to LH-40B)

thingiverse

This lens hood is a clone of the Olympus LH-40B, which is designed for the 45mm f/1.8 lens. It is reversible, and also clicks in place similar to the Olympus-hood. It is fairly tight, so may need to be tweaked depending on your printer's bias. This is difficult to print, but is possible without supports. The lugs that connect to the lens are very overhanging, but I was able to successfully print it setting the lugs (2.5 to 4mm) to have a layer height of 0.05mm. I didn't get good results with a larger layer height. The hood can be edited to place the lugs directly on the print bed, which would make it much easier to print. The dimensions are based on photographs of the lens hood, and not the actual hood, so it could be tweaked somewhat. Also, the walls of the hood have been thickened until the hood is fairly stiff. They can be reduced (the thickness variable) if you'd like a more flexible hood. As this is parametric CAD, it can be fairly easily adapted to other lens. PS: If you own the official lens hood, I'd appreciate if someone could post measurements of the lens hood (as a comment) so that I can revise this model to be closer to the official hood.
