One Small Pen Plotter
It's a nice pen holder, it's a bit absurd. Currently: stray linear bearings found in CBA basement (very flash), could be LM6UU's or similar. Linear bearings + flexure add compliance in the Z axis, meaning we dont' break our pens.
- do lm6uu design for repeatability elsewhere
- could make pen-clip friendlier / faster
- could be one big flexure
