Sorry for not responding sooner, I'll get you the files in DXF format
today. I've attached them in DWG format to this email (since that is what I
had available without conversion).
...
Some notes about the design of the light box:

You will need two of each item I sent design files for. The scale of these
files is 1 unit = 1 mm.

If you want to modify the design to better suit your scanner, you will need
to reduce the distance between the lighting module front and lighting
module back. This affects the lighting module sides, the large baffles, and
the LED base plate.

The lighting module sides should be exactly the same, but reduced in width
by whatever is necessary to make it sit on the top of your scanner.

Similarly, the size of the large baffle needs to be reduced by the same
amount along its longest dimension.

The LED base plate is made from FR4. I included it in the shipment to you.
The reason it is FR4 is that it is meant to hold the lights which means
that any heat generated from the lights needs to be accounted for.
Something that is flammable or something that might distort and change
shape when it gets warm are bad choices. FR4 is great because it is both
flame and heat resistant.

The plate I sent will be too long. You could deal with this in two ways.
One way would be to remove the slots on top of the front/back plates and
have it just rest with a bit of overhang.

Another way would be to modify the plate so that it fits. You can cut FR4
with a saw (be careful because it is brittle). You can also drill FR4. So
you could cut it in half, then drill a couple of holes to bolt it back
together as a shorter length. If you do this, be very careful of the dust
generated. FR4 is fiberglass-reinforced. And fiberglass dust is dangerous.

Or if you have access to a waterjet, you could buy a piece of FR4 pretty
cheaply and use the waterjet to cut out a modified piece. If you want to do
this, let me know and I can send you the design file for it. You can't cut
FR4 with a laser AFAIK (heat resistant, flame resistant). And it would be a
bad idea to use a CNC router to cut it out (fiberglass dust is very bad for
you). This is why we pay a shop to cut out the LED base plates in batches
with a waterjet. But it is much more expensive to cut a one-off piece of a
different design.

Or if you don't want to modify the design of the lighting module, the
alternative is to add on to the scanner some pieces that would allow you to
rest the unmodified lighting module on top. I'm not sure how much bigger
the lighting module is. But it could be a 2x4 on each side would provide
enough extra width for example. I haven't had much experience with the
older hackerspace scanners, so I don't know for sure.

DXF is probably what we need. Please send a DXF file. But if you can
include the SVG also... This is not my ken and I have not heard back yet.
thanks!

When it is on its way, I'll send along tracking information.

And I'm happy to send you design files for the plates as soon as I hear
back what format you want them in.

Hi. You can send a Paypal payment to our orders at tenrec.builders email
address. Or I can make a custom item in the store for you to purchase. It
is up to you which way you want to go.

I'll send along the design files for the main panels as well and you can
then modify them to suit your size or use them as-is and add your own cross
beams or framework to rest it on. Do you have a preferred format (DXF, SVG,
something else)?

Hi Jonathan,
I really appreciate your help and your work on diybookscanner.org where I
am trying to learn all the fundamentals to defeat my reading disability.

How do we do this with a credit card? Below is a link is to your quote. I
want to purchase the option (2) for $150 for use at Oakland's SUDO room on
the 'hackerspace' scanner which came from Noisebridge in San Fran.

Email, text or call me at 415-724-1479 <(415)%20724-1479>,
Jacques

(2) You could get the lighting module hardware from me and cut out your own
plates for the module itself. I'll provide you with DXF or SVG files. The
plates could be cut out of hardboard on a laser cutter (I am pretty sure
they had a laser cutter at Noisebridge when I visited there) and then you
spray paint them black. And you could cut them out as-is, or tweak the
design to better fit your scanner before cutting them out. I'd be happy to
give you advice as far as that is concerned.

What I would send you includes all the electrical stuff, fixtures, LED
lights, hardware, AC adapter, the LED base plate made from FR-4, lenses,
etc. So you would get everything but the plates themselves. The price would
be $150 and shipping cost to California is included in that price.
