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.

sketches And we have a model subframe which is really promising! OpenSCAD for the win! 2025-09-04 12:10:31 +01:00

tricycle-mechanical-design

Design of a highly experimental recumbent tricycle, not software at all.

Early sketch of the tricycle

Status

Still at a very preliminary, pre-prototype stage. Work is documented here.

The current model is built with OpenSCAD; to render the model, open model/tricycle.scad.

Dependencies

The following libraries are used into this model. They should be downloaded and installed into your OpenSCAD library directory, which on Linux systems is usually $HOME/.local/share/OpenSCAD/libraries.
