Macro Flash Diffusor for Olympus 60mm f/2.8 Macro

A small and portable macro flash diffusor for the Olympus 60mm f/2.8 macro lens that attaches on the bayonet mount of the lens. It allows you to still attach filters and close up lenses. It also fits the Olympus 25mm f/1.8 lens, as they share the same bayonet mount.

It's light, small and foldable and should fit in almost any camera bag.

There are two diffusor “shields” the one named “diffusor_blank” is just a 5mm thick shield, meant to be used as is, or modified in your CAD program of choice (fusion files + step files are included). You can also play around with infill settings to slightly change the light scattering.

The diffusor shield named just “diffusor” is designed to be brighter in the middle and taper off towards the edges, to give it a more natural look in the reflections of objects, insect eyes, etc. I'm not so sure how well it works, as I'm still new to macro photography and learning myself ;)

I've included a few example macro images.

The only non 3D printed parts are two M3x30 screws, adjust them to change how tight the hinge will be (don't over tighten it).

Printing instructions:

• No support needed
• Should print fine with a standard 0.4mm nozzle at 0.2mm layer height
• The shield should be printed with a transparent or translucent filament (obviously), I've used Spectrums Glossy PETG.
• The mount can be printed out of a different material, but I recommend black PETG, so that it won't be as visible in reflections. 
• The mount has small “bridges” where the hinge parts connect, those are there to prevent the generated brim to go in between the hinge, it's just there to make it easier to remove the brim afterwards, they need to be cut out.
• A note on tolerances: The Bayonet mount needs quite high tolerances to fit properly, it took me multiple test prints to get it just right. If your printer isn't calibrated well enough, you might need to adjust the size of the bayonet mount, I suggest making it 0.1% bigger or smaller.
   

Assembly instructions:

• Not much to say, put the two pieces together with the two screws, adjust the hinge friction by how tight the screws are, less is probably more ;)
