10.5mm lightpipes aren't very flexible, but they don't have to be. I think the minimum bend radius is about 70-80mm. I happen to have a local company that distributes all sorts of fiberoptic lighting supplies I was able to check it out at, but I'm sure they're just ordering direct from someone else anyway:http://www.wiedamark...resideglow.aspx
(Don't let the fact that I linked to the 'side glow' fool you. The only difference between endglow and sideglow in solid core fiber like this is whether they add another black jacket atop it. I can add shrink tubing where I want/need it)
I was planning a hexagonal arrangement: 3 pipes each side of the lens, plus maybe routing the focus lamp light to a seventh. Plus if I get creative with my collar and the lightpipe clamps, I could group them together behind diffusers (you can print transparent ABS now too) or allow the user to move them wherever they wanted. Current CAD model (the black central part is the solid of the Ikelite port outline, only one diffuser currently shown at right) is attached. One of the things I'm a bit uncertain of is if I want to risk having the diffusers stand a little 'above' the port tip. Too far forward and they'll light up the port face itself and reduce contrast. Too far back and you get port outline shadows again. The Sage fiberoptic assembly just ends in the individual fibers well in front of the port face, but provides some adjustment. Not sure I want to go to all the trouble of having thumbscrews etc. to allow that.
Not sure I was trying to make money when I bought the printer, but it would be nice to sell just enough parts to pay back the initial investment itself (mine's a Solidoodle, considerably less starting cost than the Up!), and maybe free up money by printing a few parts like this that I can spend on other things like lenses instead.
Sorry if this seems like a thread hijacking - just excited to talk to someone else doing 3d printing for u/w use. I see some of Reef Photo's parts (Reefnet brand) are 3D printed. Much as I like and respect them as a seller, and have bought from them (strobes etc), I can't see them continuing to sell things like strobe face snoot adaptors for $140 when they're clearly 3D printed parts.
