This is a remix (combining of) 2 different STL Files. I did this using my very rudimentary knowledge of Tinkercad.

Two reasons for doing this is the first stl had very sharp edges that when wearing camera on my neck would cause painon my chest if i was wearing a tee shirt. The second STL did not have way to attach without glue? The second reason is that original Eyecup provided by Olympus for this camera is a little loose and very easy to lose (which I did) and replacements are very expensive
I printed with supports using PRUSA slicer and PLA. Did not try without supports or is any other filament type.
To install it, it drops down over the viewfinder. It is a tight fit so go slow until it seat all the way down.
The author remixed this model.
