Hexagonal Pattern Weights
=========================
.. figure:: pattern_weights.jpg
:align: center
.. only:: html
.. contents::
These are pattern weights made with big washers in a 3D printed casing,
in a shape and size compliant with the `Stickers Standard
<https://sticker.how/>`_.
With the washers I can easily source they weight almost 75g and 100g for
the 3-washers and 4-washers versions respectively.
The bottom is covered with felt to protect the fabric they are used on,
and the top is decorated with any sticker that follows the Standard.
Materials
---------
For each weight you need:
* 3 or 4 washers, 38 mm in diameter with a hole of 12 mm diameter and 3
mm thick;
* either :download:`pattern_weight-3_washers.stl` or
:download:`pattern_weight-4_washers.stl`;
* a small piece of felt;
* a suitable sticker;
* PVA glue.
If you have washers of a different size you will need to get the
`openscad sources for the 3d models from git
<https://git.trueelena.org/3d/craft_tools/tree/src>`_ and adjust them.
Note that the size of the hexagon is hardcoded at 25 mm in size, and
thus the washer should be smaller than 20 mm in radius.
Instructions
------------
3D-print the plastic pieces: any regular filament will do, I used PLA,
and you can use a relatively dense fill, since there aren't many big
areas to fill.
Clean the print as needed.

Using the plastic piece as a template, cut an hexagonal piece of felt.
Put the washers in the plastic piece one at a time, making sure that
they are fitting in correctly: they should end up flush with the border
of the plastic piece.
Apply a generous layer of PVA glue over the washers and plastic piece,
let it start to dry a few minutes.
Put the felt over the PVA, press carefully and let it dry completely.
Turn the weight upside down and apply a Standard Compliant sticker on
top as decoration.
