At a tangent - how did you light the last image, with the 40x NA 0.80?
Only 0.8mm WD iirc. I assume you used epi-lighting?

Please excuse the continuation of the tangent 
I have the same parts, up to the top of the cream colored Trinoc tube.
Could you tell me what parts are not visible within, and above, please?
You have some photo eyepiece in there I assume, and the black tube - ?
thanks

Sure, the black tube is a Nikon microscope photo tube adapter PA01-12A with a Canon T-mount adapter. It has one of those 2.5x photo eyepieces in the trinocular tube. I don't normally use that setup. Meaning the tube and photo relay eyepiece but usually do with the MM-11 when using the EPI setup. I would think that the tube could easily be 3D printed or machines. They want a arm and a leg for one of those puppies. I found one on eBay for a fraction of the price of a new one so I bought it. The T-mount adapter doesn't fit like it should and I haven't looked into way yet since I rarely have used it.

Thanks
The black part's just a plain tube, with no optics?

$269.00 and it's not even flocked!
Thanks, I have some plumbing which can go on there.

Thanks Gene
That looked attractive at $20 until I saw the shipping is $67 even to the US, and I'm in the UK.
There seem to be a lot of similar-looking Nikon contraptions about; I assume that's the only one with the relevant features and fittings?

Just for clarification my pictured Frankinscope is a MM-11. I know they are similar. I wonder if the 'internal' focus gearing components are the same on the UM-2 is the same as a MM-11.
I still think it would be super simple to 3D print a tube 'exactly' as the one I posted and glue the proper camera adapter on one end.
A while back I 3D printed a Nikon MM-11 dovetail by 30.5 Tiffen filter adapter, see image below, just to see if it worked and for no particular reason. It's a Ttiffen 30.5 UV filter (number 2) that I took the glass out of, then glued it onto the 3D printed adapter (number 1). Then I reverse and screw my 28mm Schneider Kreuznach Componon on the end of it as shown below. Of course I can always redesign the 3D printed PLA adapter to make it shorter to some degree or longer.

| BTW, I don't have a manual for the UM-2, only the UM-11U and UM-22U so I couldn't verify the focus components compatibility (not that it matters). |

Oh, I didn't realise that.
What's supposed to go between the shutter unit and the trinoc tube?
I have some tubes with M42 at the top which slide in to the trinoc port well enough that I should be able, maybe some tape, get it central and grip with the thumbscrew.
The shutter appeals, for clattery Nikon cameras without EFSC.
(Shipping varies all over the place. The $67 was to a different US State, and the "estimates" to the UK are never right!)
