Aryq:

The new height is better!
The text seems a little better too -- not sure if you did anything with that or it may be that depending on the radius (i printed it at 80% size) it just happens to kern better or worse.

The new center design is better. If it's easy to do it might be nice to try one where that center is actually quite a bit higher up, to elevate cody a half inch or so.. Might be worth a try..

Also on further thought, I think maybe having the bottom flat with nothing on it might be better for when we use this as a base for the cody figurine and award, because it would allow me to write something personal on the underside with an oil paint pen. I think that would be preferable to a design, and make the printing easier.

Aryq, I had a great idea:

What if coming up out of the "coin" in the center was a small diameter rod, perhaps only 4mm diameter, coming up about 2 inches?

This would accomplish a couple of things:
It would elevate cody, for an interesting look.
It would make the rest of the coin top completely visible, so we could use all of the space including the center, for design.
With a hold at the bottom of cody (sorry old chap!) we could easily mount him on it.

With the center visible we might even move the cody with coin design that is on the bottom to the top center, OR use it for some additional (non-curved) text, which could come in handy for some awards..

mouser,
The nice thing is everything you suggest (mostly) is really easy. Comment out the cody, change the height of the column, etc.

I haven't tried it but I think OpenSCAD can import an stl - you may be able to do this in one print.

I changed the font in the latest version, from Arial Black to Liberation Mono (DC.com) and Liberation Sans (other text).

I normally go through and fix indenting and comment things before I do this

but here's the source - I included the font needed for the edge; fonts for the top will need to be on your system (OpenSCAD has a font list under the help menu to be sure).

When you're using OpenSCAD it shows a "preview" but to print it you need to do a "render" (F6 or a toolbar button) which is pretty slow with the fonts. Then you can export an STL.

Helpful tip for OpenSCAD, if you put a "#" at the beginning of a line or object then it's highlighted in red, so you can see what you're editing.

Awesome, thanks aryq!

Clever! It really made a difference.

I have openscad installed and have played with it a tiny bit. I think I will need your help making the "rod".

You can do it! Look at the bottom of the file; I've commented out a cylinder "//simple platform for Cody".

[Select]

translate([0,0,2]){cylinder (r=20,h=3,center=true);}

First change r and h - note that the height expands from the middle so it sticks out the bottom.

[Select]

translate([0,0,2]){cylinder (r=2,h=30,center=true);}

Then change the "z" value in the translate function to slide it upward. You can move it up by half the height, plus half the thickness of the cylinder. Overlap is OK.

[Select]

translate([0,0,17]){cylinder (r=2,h=30,center=true);}

Thanks, aryq. It's nice having people to learn from here

ayryq · « **Reply #56 on:** March 30, 2018, 07:12 AM »

Here, use this one instead. I got rid of all the "center=true" so things grow "up" instead of "out". Should make dimensions easier to play with.

Great, thanks Aryq -- I'm having fun playing with it now

Heralding a new arrival:

I have to say that the idea of a rod and perching cody above it did not work as well as I had hoped -- he looked a little strange sitting on a pole so I had to put him on a second tier. Probably more trouble than it's worth, as the look of him just sitting on the coin base still seems best to me.

I will soon try painting one of the baby codys.

mouser · « **Reply #60 on:** March 30, 2018, 07:45 PM »

And then we have to figure out what awards to make and who gets them.. It won't cost much to print or ship these, but will take quite a few hours to print each one. If they are to be painted, much more work involved.
We could offer them as alternatives to NANY mugs.. But maybe their best use would be as special awards for long time dc forum members who have made thousands of posts, or forum moderators. Or big shot donors

They can be customized with username, date of joining, etc, etc..

Nudone did such a great job with the baby cody model, I still can't get over it.

You should try acetone-fuming with one of the codys. It smooths out all the ridges and makes it much easier to paint. Lots of info online; I did it with a widemouth mason jar on my heated bed and a little lower-able platform made of stiff electrical wire.

Edit: this is for ABS. good link here: http://blog.reprap.o...ng-abs-rp-parts.html

Those pics remind me of chocolate Easter Bunnies so we need to find some chocolate filament (I wish) and make a Choco-Baby-Cody. Hahahaha.

I've seen those dedicated alcohol smoothing machines (they require special fillament).

Aryq, I'm having a lot of fun with the coin scad file -- I am making most things proper options instead of hardcoded values.. I will send you my file when I am done.

Update: I'm *loving* OpenSCAD - a programmer's dream cad program. I've got most of the coin options nicely configurable now so you can more easily change the sizes of different things. I will share soon.

These aren't too laborious to produce.. Some spray paint, oil marker, and hand painting the beak, feet, and eyes.

I'll try some more sizes for cody and the coin...

Text on coin face and around the rim are customizeable.

So, it seems to me I could make a couple dozen of these with custom text and send them out to special folks.

not sure what Stephen is saying, but I *probably* agree with him...
Definitely agree with Deozaan though
