Backscatter Miniflash adapter for Atom Strobe 

Convert your OS-1 Miniflash snoot to work with your Atom Strobe

https://makerworld.com/en/models/2718050-snoot-adapter-os-1-to-atom-strobe#profileId-3010574

I have had the Backscatter Miniflash MF-1 and MF-2 strobes for many years and love the OS-1 Snoot that this small strobe was designed around. It's probably the best snoot on the market, accurate and easy to use. The new Atom strobe is more powerful than the Miniflash models, but not much bigger. It's pretty much replaced my MF-2 strobe.

But I really didn't want to buy the new OS-2 snoot for it. It turns out that the new model uses the same exacted optics and lens module as the older OS-1 snoot. It just uses a new mounting part to attach to the strobe. I have designed an adapter with very similar dimensions as the OS-2 snoot, and it works perfectly. The light cards from the OS-1 will also work in the updated snoot. 

 

Directions:

Remove the four M3 screws that hold the aluminum optics front end module from the OS-1 snoot. You will need a 2.5mm allen key wrench. 

 

Use four M3 20mm screws to attach the adapter to the OS-1 optics module. Do not over tighten, just slightly finger tight. Do NOT use a screw longer than 20mm or you will very likely crack the glass in the optics module. 

 

Filament Choice:

I strongly suggest using the recommended PETG for this model. PLA might work in the short term, but PLA does not wear well in the water and sun.  It might break unexpectedly when exposed to the elements. 

 

HI Dave

Now there is a timing coincidence. 😊

I competed the final (I hope) print of my Z330 adapter for the OS-1 just yesterday.

The optical element has a bayonet mount so that I can use less extreme restrictors - yet to be printed.

I fully agree with the careful selection of screw length - while 'prototyping' I trashed the supplied optical element and had to make a plexiglass replacement ☹️.

I also printed an 80mm beam restrictor (wide snoot) but am not sure if that is going to be of any use. Still, for a few cents of PETG why not.

Testing due in Sulawesi in June . . . current Geopolitical disturbances allowing 🤞

Keep up the good work

Cool, i love the style! Have you tried it out? The offset spotting light always made the Inon strobes tough to snoot with. Hopefully the lens in the OS-1 compensates.

I have been using the Atom Snoot for a few months now, i just forgot to share it!

I tried an early version but had 2 problems:

1. I did not make the adapter suficiently eccentric so the spotting light was very weak - it is a lot stronger with the maximised eccentric offset.

2. As you warned! due to the screws being too long I managed to trash the optical element ☹️

I will keep going with the Inons until I burn out the tubes (which I managed to do on quite a few 240's) then I suspect a jump to 'hybrid' flashes will happen.

Just keeping my fingers and toes crossed that I will be able to get out to Indonesia in June.

How difficult would it be to adapt to a Z240?

Hi Grantmac

It is certainly possible with some redesigning or an additional interface element.

I just dug out one of my 'back-up' Z240's and offered my Z330 adapter up to it. Obviosly there is no bayonet feature though the 2 filter mounting threaded inserts could be used to attach it BUT then it would be difficult to center the spotting light to the snoot and as this is only 160 Lumen the light is resultant spot is quite weak.

A better option would be to modify or add an extra element to the adapter so that it is a larger diameter and a push fit over the front rubber protective ring. This would make it wider but allow for better aligniment of the spotting light and the optics.

I have just added 2 other snoot elements 77mm and 34mm to my 'work in progress'

Sorry Dave - I did not mean to hijack your post.

Looks like underwater light and magic makes a converter:

Underwater Light and Magic

INON Z240/D2000 to Z330/D200 Strobe Converter

This converter enables older Z240/D2000 strobes to be converted to use the Z330/D200 fitment, making them compatible with all Z330/D200 accessories available in our store, including beam restrictors,

I don't know if it would have the strength to carry a strobe however.
