How well do 3d printed funnel style snoots work?

[shokwaav]

I've got a Backscatter HF-1 on order, but their snoot isn't available yet until later this year.

 

I planned on designing and 3d printing one.

 

The simplest design seems to be a funnel style snoot, but are there disadvantages to this design?

 

Also what type of material would you print it out of? PETG seems to be the favourite, but would something more matte like CF-PETG or Nylon be a better choice?

Hi shokwaav

 

The problem with homemade snoots is the aiming system.

 

I think lots of us have had a go - I used plumbing piping. A really fun project but it's almost impossible to aim the snoot correctly even when the strobe has a focussing light. 

 

The best snoot/strobe combinations have a circular flash tube with the focussing light in the centre. (Check out the Retra combination). This is very good for lighting the subject pre-flash and then close to ensuring the strobe light will illuminate the same place. 

 

if you can manage that with a homemade system, then you have a fighting chance. Otherwise, frustration lies ahead......

 The Backscatter HF-1 has a snoot LED mode, but looking at the LEDs, they're slightly offset from the flash. I think they might be slightly angled inwards. 

 

From the manual:

Note: The Snoot LED light mode is designed and optimized for use with the Backscatter OS-2H Optical Snoot to allow the brightest transmission of light aiming through the snoot. The spot target light is primarily designed to work with the OS-2H optical snoot, but can also be used as a target light for up close macro use. The Red beam may also be used with the snoot.

I had used a 3D printed version of a snoot... for about one trip. That kind of might be a hint of how much I liked it 😉

 

After that I purchased the Retra snoot, and have been set for all those years since then.

 

It starts with the handling: the 3D printed solutions will most likely float. If you want to take it off, it will almost always go to places where you don't want it to be. It was a constant annoyance to me. With the optical snoots, you just clip them away.

 

There is also no contest in aiming the snoot: the optical snoot will be so much easier to aim and that was what immediately sold me to it. Because aiming a snoot is always a challenge, especially while using one for the first couple of dives. If you have a strobe with a focus light in the middle of the strobe and use an optical snoot, it ist much much easier and will give you a lot less frustration.

 

The next thing is flexibility. With the optical snoot you get different light options by just changing the distance of the snoot to the subject. The edge of the light will be very different. You can have it wider with soft edges or very sharp with a hard light fall off, just by altering the distance. Without optical elements in the snoot, I don't think that is possible.
