So actually the center of the coin won't be too visible I guess, since cody will be on it.

What about the bottom? That could have a nice/fun design for an extra treat to those who pick up the coin+Cody and take a look at the underside.

The first openscan coin model with text seems to use this Write library: https://www.thingiverse.com/thing:16193
I don't know about the others.

(the fancy one with text on the side seems to use something different -- not only that but it uses a 2bit png image as a mask for the engraved center image!).

ps. We should split this 3d printing discussion into its own thread.

The first sample coin thing does actually have text on the bottom.

Or give it some mirrored text&image so it can be used as a stamp?

Text on the bottom/sides is easy to design and render, less easy to print.
the write.scad library is nice because it does curved text for tops and sides of cylinders, but it has a weird format for fonts and doesn't look like it kerns correctly.

Have you tried that fancy coin one? It seems to use normal fonts AND that ability to use a png bitmap as a raised image is really nice.

I found a better library to use:

Updates as they become available

Excellent.

Nudone has been hard at work, look at this little baby cody model!

Good to see you back.

Here's what I'm working on. I'm happy to receive creative direction!

mouser · « **Reply #38 on:** March 29, 2018, 04:34 PM »

Looking good, aryq!

Here are my suggestions:

1. I think the DonationCoder.com text might look good if it was same orientation at the other. I do like how you have one inset and one embossed.
2. The underneath image is cool!
3. The center image might be better as a raised "$"
4. The text around the edge.. maybe better as just one row of 0s and 1s rather than two?

mouser · « **Reply #39 on:** March 29, 2018, 04:35 PM »

When you are ready send me an stl and i'll print out a copy and put baby cody sitting on top of it and we'll see what the completed model will look like..

ayryq · « **Reply #40 on:** March 29, 2018, 07:40 PM »

I think this is what you meant:

I had the plain center to serve as a base for Cody (edit: with the hex socket for some sort of peg); I'm not sure how it'll look with him sitting on the $ sign. Also, the symbol is pretty US-specific. Maybe kill two birds by using the "currency" symbol i.e. "¤" instead. I spun the text around as well.

I need a test print to see how these small bits look. Currently the size of the coin is 76mm, about 3 inches.

Ditto!

mouser · « **Reply #43 on:** March 29, 2018, 08:04 PM »

I like the $ though as you say it is US specific; but we could change it based on the award. AND most importantly, the current plan is to have cody sitting on it so the center may not be very visible/readable anyway.

I think it really looks nice!!!! I'm anxious to print out a copy myself.

mouser · « **Reply #44 on:** March 30, 2018, 01:36 AM »

Printed out ayryq's latest coin -- though it's more of a thick beveridge coaster sized disc, with and without cody on it.

Looks pretty great. Painted up I think it would look amazing.

aryq, the coin came out great!

It's HUGE. and I think probably twice as thick as it needs to be -- at least if its going to be printed at this size. I might scale it down from 3 inches to 2 and try printing it again. The bottom actually came out nice this time.

The only thing that is not great is the font kerning and alignment -- as you suspected. It's a bit wonky, though if there was no fix, we could live with it.

Thank you so much. Can't wait to see what it looks like painted up.

Since cody takes up most of the center of the coin -- we might just put a smaller round pedestal there.

The side numbers printed fantastically.. Makes me think we should either come up with some custom text for that OR at least make the binary code MEAN something..

ayryq · « **Reply #46 on:** March 30, 2018, 02:53 AM »

OK, this one is thinner (5mm) but just as large, has a gear-looking thing for the pedestal, and has a chunkier, simpler cody on the bottom. I switched the font but no matter what I do that "e" in "coder" is high. Since that text won't change maybe I'll make it in Inkscape and bring it over as a dxf. It's also not manifold, and I don't know why, but it sliced fine as far as I can tell.

It's far more important that I be able to change the text easily (in openscad) than it is for the text to be laid out perfectly, so given the choice let's live with the text kerning weirdness.

I will print this one out as soon as my 66% sized current one finishes.

I need a cody coin in my life...

mouser · « **Reply #49 on:** March 30, 2018, 04:15 AM »

Aryq,

For testing purposes it might be good to get rid of that bottom cody pattern -- my printer has a hard time printing it reliably and tends to get tangled there.
