Wax Coupler for EggBot
This EggBot accessory solves a unique problem: If you take an egg (or
other spherical or egg-shaped object that you are printing upon) out of
an EggBot and put it back in, it is challenging to get it precisely
lined up in exactly the same place. Normally, that's not an issue— when
you draw with pens, you leave the object in place, and take the object
out only when it's done.
However, things are different when using
the Electro-Kistka for EggBot. The Electro-Kistka is a hot-wax "pen,"
used in the traditional wax-resist and dye (batik) method. In that
process, you typically apply wax to the egg, dip it in dye to color it,
let it dry, and then repeat with progressively darker colors of dye. And
in doing so, you end up repeatedly removing the egg from the EggBot and
putting it back in place.
The Wax Coupler for EggBot makes this
process much easier. It is a specialized replacement for the "egg
coupler" that connects the egg (or other spherical or egg-shaped object
that you are printing upon) to the "egg motor" that turns it. Rather
than having a soft surface, it is made of solid aluminum with a
three-pronged face. To use it, you center the egg in the coupler (as you
normally would) but then securely attach the Wax Coupler to the egg
with wax. Then, when you need to remove the egg, you unscrew the Wax
Coupler. The Wax Coupler stays securely attached to the egg when you dip
it in the dye, provides a stand for drying it after dying, and then
provides registration when you go to put it back on the EggBot.
order to provide good registration, the Wax Coupler uses (1) a flat-tip
set screw that indexes against the flat side of the EggBot's motor and
(2) an included 5 mm shaft collar that provides a consistent depth stop
for the Wax Coupler.
