Mind you the U.S. seems still to be full of small workshops run by nice Jed Clampett kind of guys who will willingly turn their hand to any problem a customer turns up with

The U.K. or certainly this region of the U.K. seems to have none of the small engineering shops left

2. Someone with access to a school 3D printer and a bit of spare time was able to make me a superb model of Ralph Lambrecht's test strip printer. Ralph has freely given out the details for anyone to use to construct a printer

So I never made the connection but should have between what a school has and needs for its design and technology classes compared
to what is available and within the average budget of a home user

Well, as I say, making a few items for yourself will be OK (I don't know what part the OP has in mind so can't tell if it is suitable for a home 3d printer). It's just that in general, the slow speed and relative low finish quality rules out commercial use of this low-cost type of printer.

Perhaps when I get mine working again I can look at what might be involved in a one-off 4x5 easel! Should make an interesting project which, while it will not be as good as an injection moulded item, should still be useable.

I made one of Ralph Lambrecht's test strip printers out of mount-board many moons ago now - it's still going strong .

Thanks for your replies, I've now had an offer of help. In fact the item wasn't of photographic significance.

I notice the various mentions of negative holders. I wonder if CNC machining from aluminium alloy might work better for such precision items? - it's also a lot quicker than 3D printing.
