Spent some time working this out on the whiteboard today, and threw together some rhino sketches.

I'm going for simple, strong-enough, and easy to build. Using rollers and pulleys, or, just as easily, rack and pinion or leadscrew-type actuation.

also uses long M3's for tuning, nuts, washers. Length to be selected.
### Egregious Errors
- bottom rail extremely unhappy, should be smooth and sideways ways should be clear
### Minor Errors
- missed a few holes in CAM, double check!
- y block internal boxing has co-dependent assy
- bearing bushings not satisfactory
- on double rollers, accomodate washer in between
- motor collar coule be +0.05mm in diameter
- need long M5 for motor -> bearing
- need bigger wall on captive nut for tuning
- need channel in side of motor collet for screw turning
- XZ situation has lots of unaddressed assembly issues
- add clamping features, hole access for final beam -> gantry assembly
- have to watch where bolt heads, bolts are - should include those in kinematic units modules
- y gantries should include two rollers in xy space (machine space) constraints
## Some Simulation
It occured to me in class today (Rob Hart fabricated the below component!) that the two-bar flexure I had intended was acting much more like a one-link flexure. Whoops, all well. Still does its job. Here's an image of that in any case:
