This part works, new toolchanger feels good also.

Revisioning this to bring it up to speed with toolchanger deltas, also found a new loadcell to suit the smaller toolchanger design, that's UXCell PN `a15110200ux0247`.
So I've to revision to tighten this up, but it should be pretty straightforward. I think I do this, then fab it all, and can bring loadcell probes in to the mix once I have two of these swapping pretty well... would love to have i.e. an 0.8mm infill tool and 0.4mm perimeter tool.
- adjustment for smaller loadcell,
- adjustment to hotend pinching clamshell
- rm interference between hotend / bowden top and loadcell
- more-better planar constraint on hotend / coolside / front-of-hotend clamshell
Great, this is done, so I'll fab and then bring heaters & loadcells online.

Assembled one of these, have some hardware bugs but will continue to bring this online instead of revisioning:
