That XY Table I said "Don't print this model, it's only a mockup"? Well, I had the model and there was a printer next to me. It kinda happened. In my defence I only printed it at 60% scale.

 

If you're also going to not print it, I warn you that my flexures were just eyeballed for the sketch and are too thick causing unwanted resistance/rotation. Also it needs a base of some kind (preferably with diagonal bracing) to stop the bent flexures digging into the floor. Other than that it moves surprisingly well.

As I say, needs connections and mounts for axis drivers. But, uh, wow. Useful exercise. I'll keep it around to model in OpenSCAD if nobody else does it hint.

Now, stop playing with it Vik, and get on with the resin experiments. 

I've had this buzzing around my head for a bit. By clever arrangement of the flexures, I think it might be possible to print-in-place the XY Table. So I roughly (really roughly) drew this up in Tinkercad, which is really quite good for 3D sketches:

The green bit is the stage, yellow bits are flexures, red bits structural beams, and the grey bits will be hollow boxes but I've made them see-through so you can see the guts. The outer hollow box is the frame.

If you fancy tinkering yourself or looking at a 3D view, I've stuck it on the Fab Lab's public area:

Attaching the X & Y Axis Drivers is left as an interesting exercise to the enthusiast. Again, this is just a rough mockup of an idea. It's not meant to be a real printable thing. Do feel free to fix that...
