Simon Brooke 5231893347 Tightened up components in the subframe; added a sketch showing how the
subframe might mount.

Simon Brooke ad7c766b2a Changed the illustration in the README to represent progress. 2025-09-07 08:40:49 +01:00
Simon Brooke 8a6a6be54f This is tentative: I've moved the subframe back to the origin of the grid
in its own model, although I haven't yet lifted it so that its wheel sits on
the ground plane. I've rescaled it so that the wheel is the correct size.

I think each individual model should be build to the grid origin within its own
file, but that major components (subframe, fourbar) should be at the correct
vertical height for final assembly.

Simon Brooke 113546782f I've written a hull which in itself isn't dreadful, but which has revealed
fragility in the way OpenSCAD handles name collisions. This makes mixing
libraries highly problematic. Needs thought.
