Dividers
========

Dividers are added to the frame to make compartments.

Divider panels
--------------

Dividers are assembled from panel parts and caps. For each divider, print the
necessary panel parts, one left cap, ``CapL_Hh.stl``, and one right cap,
``CapR_Hh.stl``, where ``h`` is the panel height, e.g. ``CapL_H5.stl``. To
determine the required panel length, count the visible top squares holes in a
panel that runs parallel to the planned divider, substracting two to account for
the caps and grooves.

Grooves
-------

Grooves are connected to panels with pegs. For each divider, print two grooves,
``Groove_Hh_Ii.stl``, where ``h`` and ``i`` are the panel height (in cm). (See
:ref:`mixing-panel-heights` for the distinction between ``h`` and ``i``.) Two
round pegs are also needed for each groove, and are provided in the 8-peg
cluster, ``Peg_x8.stl``.

To facilitate pushing pegs into a groove, first put the pegs in a panel part
lying flat (a). Then, push the groove down onto the pegs (b).

Insert the grooves in the frame, opposite one another (a). Then, slide in the
divider (b).

Subdividing the organiser
-------------------------

Corners, caps and grooves are designed so that parallel panels are always spaced
by an integer number of cm, measured between panel centres. As a consequence,
dividers can be added to the frame and to other dividers as desired, until a
compartment is too small to be further subdivided.

Mixing panel heights
--------------------

Dividers of different heights can be used in the same organiser, the only
restriction being that a divider can be added to a panel only if that panel is
taller or of the same height. This implies that no divider can be taller than
the organiser’s frame. While taller compartments are more sturdy, shorter panels
make it easier to pick objects up.

To insert a divider of height ``i`` into a taller panel of height ``h``, use the
corresponding ``Groove_Hh_Ii.stl`` part.

Grooves for 3-cm inserts are used with :doc:`waves` rather than dividers.
