Inspired by Larry Heyda's venture into CAD and solid-model
rapid prototyping (which he used to create his 3D Advantage),
I thought I'd try to borrow some of his concepts for my 50mm
viewer.

Of course, I didn't have Larry's huge budget so my results
are a little more modular and less elegant. Still, I've
managed to incorporate adjustable lens spacing and focus in a
steal-the-light viewer.

But seriously folks, it works and I now think it's worth
building a real viewer around those lenses. The sweet-spot
on the lenses is small. The real design will have to
incorporate adjustable lens spacing as well as adjustable
slide height (image center on the 80x132 is lower than on the
80x140 mounts).

Impressive ! I gather you used the well-known Lego 3D software to
achieve this ?

Aren't Lego's great?
Now who wants to build a camera with Lincoln Logs? Designed on an Etch-
a-Sketch?
