Advanced Design - "one-size-fits-all-heads"

The first openKMQ design was sized for big adult heads and flexo bands could be used to make it fit smaller heads. The next step was to provide 3 different sizes with every kit.

Now a single layout has 8 slits to place the KMQ prism viewer in.

The new design will soon be available for free download as EPS/SVG for laser cutting or in my online shop as precut kit

Convert a dual screen to an affordable hiRes stereo LCD

I recently built my first DIY Over/Under LCD. Instead of placing two LCDs side by side, I mounted them on top of each other and added a constant distance KMQ holder.
For normal work, I still have the real estate of a dual screen. And for S3D viewing I simply pull down the KMQ holder and place my forhead on a soft cushion.
It needs some optimization because the panels are best viewed at from above, not from center level. When modified, I'll post images and a DIY instruction PDF.
