Gelbart Linear Stage

Dan Gelbart is an amazing engineer, designer, and entrepreneur.

In the included screenshot you can see a photo of the linear-positioning stage he created, which I've attempted to reproduce here with some minor modifications.

This is designed to be a demo object and would need to be modified to take into account material selection.

I don't recommend 3D printing this in plastic. Most hobbyist 3D printers will be unable to print the thin .010" walls needed to build the thin-sections which makeup the flexures that make the device work so well. Actually those walls are probably thinner than they need to be, so it may be possible to make this is plastic after all.

Ideally this design would be cut on a CNC waterjet cutter out of a single block of metal.

The major modification I've made to Gelbart's design is to expand the size of the stage mounting holes for 1" square optical mounts, giving you a 3x3 mounting pattern, and the 4 in-pattern mounting holes around them. Most optica
