Olympus TG flash cover
« on: January 10, 2019, 04:15:08 pm »
I have just purchased an Olympus TG5 following it's great reviews on here. I intend to use it with remote flashes, either using my old fireflies or the Yongnuo type flashes. I blame all of this on winning a Peli case from the UKC hidden earth raffle. I need something to put in it!

Anyway, I have keenly followed various threads, but this one has been of particular interest regarding the use of a Tg camera with a Yongnuo flash here: https://ukcaving.com/board/index.php?topic=24506.0

The TG series of cameras - at least 3, 4 & 5 have a removable bezel in which you can attach various addons. I have used this attachment as the basis to design and 3D print a couple of covers which can easily be attached to the camera without tape etc, and also allow it to be as slimline as possible to keep the overall size down.

I have done a couple of designs to test out. The first is a lens cover which opens up to screen the flash. The second is a fixed cover for the flash.

They both allow a little bit of light through the print, but it is highly diffused and even across the shot. As they do not cover the flash fully they allow quite a bit of light out - outside of the camera angle, so hopefully they will let out enough light for a flash to see. If not it is easy to add a hole in the covers to glue in a bit of film.

This is a work in progress and I have no idea when I'll be able to test them out properly.

Let me know your thoughts.

Is the hinge printed in place or a snap fit?

If I had any sense at all thats what I would have done. Yes just needs the hole for the film piece.

I think you could sell those but I imagine 3D printing items like this takes a while.

There is a ring flash accessory that fits to the lens mount. Possibly that could be converted to carry the film blank instead.

Very interesting beardedboy, keep experimenting! I'm sure there are plenty of us who would be interested in getting one of those off you.

Yes! I wonder if the TG-4 has the same fitment. I think it does as the accessories are the same. We have 2 TG-4's in our household and they are caving cameras, so take a beating. I'd be interested in paying for something like you've done above, especially one with a hole to tape an old bit of filter/film over.

Thanks for the positive response.

So to answer a few questions...

I've printed the yellow parts separately and used a bit of the raw printing filament (1.75mm) as a hinge pin. Figured that this would be the most robust solution at this scale.

I belive that these would fit on either the tg3, tg4 or tg5 as the attachment is the same, however I am not sure about the physical location of the flash.

The grey one was inspired by the ring flash, but does the exact opposite.

They don't take long to print, about an hour, but they need quit a bit of post processing because of overhangs, hence I will keep playing with the design. They grey one is obviously much simpler.

I'm more than happy to share the files once I am happy with the design.

The Yellow hinged version looks good, I'm quite happy with 35mm film over my flash, but your yellow lens cover will help stop getting the front lens covered in mud and having to try and find something clean to wipe it with.

I have made a few iterations of the hinged cover and had a little play with it underground.

I have added a couple of photos. The first shows the camera used with the flash exposed and the typical back splatter, the second, taken immediately after shows the spill that comes out of the side of the cover. I found this to be enough to trigger my Firefly3 slave with no trouble.

I have uploaded the files for 3D printing it to Thingiverse now too, so please help yourselves.
