Some have asked " what can I do with these? "

Try this....

If you have access to an overhead projector. Print the drawings on a piece of clear plastic , project them on a wall to a accurate size( like the length) and trace them on a piece of paper. Most of the dimensions are not important. It's all in the alignment of the lenses and light.

You can notch the sides and screw into the step, instead of the slot that runs the length.

Rear fresnel , glass, and LCD support. This design will fit the newer style of fresnels available in the LL store ( square corners). The glass or Lexan is the same size as the lenses.

Here is a diagram of the air path thru this setup. The green parts can be placed where needed. In this configuration the room air is entering thru the bottom, between the green and blue dividers. The light box is on the left side, the covers and sides have been omitted.The LCD and forward is isolated by the blue strips above and below the panel. The panel (illustrated in red) is attached to another a vertical strip with Silicone that slide into grooves in the side. This floats the panel and allows removal, it also may prevent twisting the panel.
