Potential early crystolecular building blocks

Extruded 2D building blocks

Self centering building blocks

Special geometry example. Snowflake building lock emplpoying the multi V groove self centering principle.
Converting weak sliding vdW force to strong ripping vdW force.
A bit like Borromean rings.
Once one part is out the others can be slid out.
Note that this is a 2D example.
Assuming mostly in plane loads or some in-plane horizontal constraints.

Puzzle pice building blocks

This should be self-explanatory.
Design principle of passive pretension.
(TODO: To investigate: Are negative stiffness bearings principles applicable?)

Slot in plates

Some research done on that at the meso/microscale by MIT CBA (center for bits nd atoms) Nanoscale it would not be friction holding the plates together but vdW forces or more strongly clips.

Preferrybly the clips lave some pre-tension to give the connections good stiffness.

1D chainable reciprocative pseudogears

This crosses over a bit into Potential early crystolecular mechanisms.
See page: Reciprocative pseudogears

The core idea here is to use the meshing of the
linear rack-gear teeth as form-closure-connection. Fallapart is constrained by vdW forces and or channel walls.

Q: How to do the interlocking assembly of matching channels segments?

Apply the desingn principle of multi V groove self centering.
Long weak bending spring pressing gently into centered position.

Space-filling polyhedra holding together via vdW forces

See page: Polyhedra of peculiar interest
Side-note: These may also be of interest for much later much bigger much more advanced microscale microcomponents.
