The Original Egg-Bot kit is the product of many years of evolution, dating back to the first Eggbot,
developed by motion control artist Bruce Shapiro in 1990. The present kit was developed by Evil
Mad Scientist Laboratories in cooperation with Bruce Shapiro, Ben Trombley, and Brian Schmalz.
This kit is designed to allow you to draw on spherical & egg-shaped objects from about
1.5-4.25” (4-10 cm) in diameter. Internet access, simple tools, and a recent-generation computer
(Mac/Win/Linux) with a USB port are required.
This assembly guide covers the procedures for putting together your Eggbot Kit. Typical assembly
time is estimated to be 1-2 hours. Please exercise appropriate care when building it: The kit
contains many small parts and some parts that could be sharp. Keep out of reach of small children.
Older children and teens may require adult assistance.

Assembly Guide
Your kit came with a bill of materials: an up-to-date list
of what’s in your particular kit. The exact items may
differ very slightly between versions of the kit.
In the instructions, we refer to components by their line
item number on the bill of materials. For example, #1
is the chassis-- a set of five fiberglass pieces.
STEP 0: It’s the BOM.
[Egg-Bot Kit Assembly Guide]
STEP 1: Tool Checklist
Essential tools: Needed to build and use the kit:
1. Small Phillips head screwdriver(s)
There are several places in the assembly process where you
will need to provide a small Phillips head screwdriver. You may
find it helpful to have a couple of different sizes handy.
3. Electrical power
And if you’re so inclined...
2. Computer, Internet access,
USB port....
To use the Eggbot, you’ll need a reasonably
recent vintage computer (Mac, Windows, or
Linux) with an available USB port as well as
internet access to download software.
All of the software that you’ll need will always
be available for free. Visit http://egg-bot.com/
to get started.
Wire strippers, soldering iron, etc.
Rather than using cable ties, you may want to reduce the length of
the wires on the stepper motors. If you’d like to trim, strip, and tin
the wires, you’re certainly welcome to do so.
The Eggbot kit comes with a regulated universal-input
power supply that accepts worldwide voltages and puts
out 9 V DC at up to at least 1 A. (International users
may need to supply a plug adapter to fit the prongs into
local outlets.)
If you’re using your own external power, make sure that it provides
9 to 18 V DC, has a center-positive plug and is rated for at least
1000 mA. (A 12V car battery with the right connector can do the
job, for example.) Please be careful: Inappropriate voltage or
polarity can cause permanent damage.
Suggested tools: Recommended; not required
1. Masking tape & Scissors, or Glue
There is a place in the appendix where you can-- optionally --use some
little strips of masking tape as shims or glue (5-minute epoxy, for
example) to fine-tune the performance.
2. Small cable ties
The wires on the stepper motors are long. There are mounting
holes provided in case you want to tie them up with a couple
of small cable ties.
OK, Let’s get started! >>>

3. Containers to hold small parts
Small bowls, an egg carton, or an array of paper cups may be helpful
for organizing small parts while you put the Eggbot together.

STEP 2: The first three parts
#2 5/64” Ball-end hex wrench
#3 3/32” Hex wrench, nickel plated
Beyond the tools already mentioned, two
additional tools are included in the Eggbot kit:
A 5/64” hex wrench and a 3/32” hex wrench.
You’ll use them frequently.
The chassis is made of fiberglass and copper.
Its edges may initially be sharp, both from how it’s cut, and
from any residual tabs– little bridges that held the parts
together during manufacturing. We’ll address that in the
next step, but please handle with care in the mean time.
This is the Eggbot chassis, #1 on your
BOM. It consists of five separate pieces.
[Egg-Bot Kit Assembly Guide]
STEP 3: Deburring the chassis
Use the nickel-plated hex wrench (the shiny one!) to
remove any sharp edges from the five chassis pieces.
Rub the wrench along each chassis edge at a 45° angle.
Usually one solid rub on each edge is sufficient to
break any sharp corners.
Nylon split bushings, part #4
STEP 4: Split bushings, part I
The two nylon split bushings, part #4, go into
the two of the chassis pieces indicated, from
the sides labeled with the big black circles.

(This piece is called the tailstock foot)
(This piece is called the tailstock brace)
STEP 5: Split bushings, part II
[Egg-Bot Kit Assembly Guide]
To install one of the bushings in the chassis, twist it as
shown, so that you can insert it into the hole, one edge at
a time. They “snap” into place, and it will be clear when
they’re installed correctly.
If necessary, the bushings can be removed by a similar
process-- by pushing one edge of the bushing in and
through the opposite side of the chassis board.
STEP 6: Test-fit the dowel pin
Part #5 is a 1/4” diameter steel dowel pin.
In the unlikely event that it does not fit
easily, do not force it. Instead, double-check
that the bushings are fully seated and try
again.
(If the problem persists, please contact
Evil Mad Science customer support for
help: contact@evilmadscience.com )
Carefully insert the dowel pin into each of the installed
split bushings. The pin should slip easily into each of
them and turn freely. Assuming that this is the case,
set the dowel pin aside and go on to the next step.

STEP 7: Screws and Standoffs
[Egg-Bot Kit Assembly Guide]
In the next step, you’ll need the four
threaded aluminum standoffs, part #6. You’ll also need 8 pieces of part #7, the
1/4” length stainless steel button socket
cap screws. (There are a total of 21 of
these in the kit.)
Be careful to use all screws of the same
length: The Eggbot kit also contains two
similar but slightly longer screws that
you will need in a later step.
Here’s how it looks once all four are added.
STEP 8: Adding Standoffs
[Egg-Bot Kit Assembly Guide]
The screws go into the four holes
shown, from the side that where
the holes have solid outlines.
Holding each screw head with a fingertip,
thread on the standoff from the opposite
side, where the holes have dashed outlines. Do not tighten the screws (yet).
