Frame
=====

The frame is the organiser’s rectangular perimeter. It is made of four panels
with corners.

Choosing a height
-----------------

Measure your drawer’s height from its bottom to the bottom of the cabinet’s face
frame. Round down to the nearest cm. This is the maximum organiser height your
drawer can accomodate. However, if you choose this maximum height and your
drawer does not open out fully, it might be necessary to assemble the frame
inside the drawer, and it might not be possible to slide it out without
dissassembling it.

When choosing a frame height, also take into account the necessary clearance to
slide dividers in. If you do not allow for enough space above the frame, you
might have to slide some or all dividers into the frame before inserting it into
the drawer. Dividers can be shorter than the frame, e.g. a 7-cm frame with 4-
and 5-cm dividers. See :doc:`dividers` for details.

The recommended frame height is 5 cm. Since this fits almost any drawer, it
favours reusability. Taller compartments consume more material and are
unnecessary in most cases. Choose a taller frame if you intend to pile objects,
or if you want to make the frame more sturdy, such as for heavy objects.

The minimum organiser height is 4 cm, as the design does not allow for shorter
panels. While there is no theoretical upper limit, the maximum height included
in the mesh files is 7 cm.

Parts of a given height are grouped in the corresponding subdirectory, e.g.
``Height5``, ``Height6``. This includes braces, caps, corners, grooves, and
panels.

Once you have choosen a height, print eight corner parts, four left and four
right. The filenames are ``CornerX_Hh.stl``, where ``X`` is either ``L`` (left)
or ``R`` (right), and ``h`` is the height in cm, e.g. ``CornerL_H5.stl``.

Width and depth
---------------

Measure your drawer’s width and depth. Substract 2.5 cm from both measured
values to account for corners, then round them down to the nearest cm. These are
the lengths you need to print panel parts for. For example, if your drawer
measures exactly 40.5×45.0 cm² (width and depth), you need two 38-cm panels
(plus corners) and two 42-cm panels (plus corners).

Panel parts are available in lengths of 1, 2, 4, 8, and 16 cm. Filenames are
``Panel_Hh_Ww.stl``, where ``h`` is the height and ``w`` the width, e.g.
``Panel_H5_W16.stl``. Print the smallest possible number of parts to get the
desired total length. Continuing the above example, each 38-cm panel should be
assembled from two 16-cm parts, one 4-cm part, and one 2-cm part (2×16 + 4 + 2 =
38).

Assembly
--------

Start by assembling the panel parts and corners to make four complete panels
(a). This is easier if you lay the parts flat. Then, join the panels at their
corners (b). If your organiser is tall, this second step might need to be done
inside the drawer. Finally, secure each corner (c) by inserting a short piece of
filament (1.75-mm diameter) in the hole that goes through the box joint.
