Post Kongos LED Gondola for Light Paintings

All the kids are making "light paintings" these days, so why not us polargraphers?

Here's a 3D printable gondola for mounting a LED that is turned off and on by the "pen lift" servo. That way there's no need for a separate "light painting" branch of the firmware.

The 3D files necessary for printing one can be downloaded from here:

PolargraphLEDGondola_Render

PolargraphLEDGondola_3Q

Low Poly Light Painting on Polargraph

PolargraphLEDGondola_Front_adjusted

Low Poly Circuit Night Sky Light Painting

I'll add more photos to my photostream and the drawbots group soon.

If anyone would like a print of this thing, but doesn't have access to a 3D printer, let me know, and we'll work out a price for it.

So, Thingiverse is working for me again, and I got the project almost ready to go live, but then I hear that Stratasys has launched the first salvo of legal attacks on their competitors.

Now I feel like using Thingiverse is tacit support for Stratasys' business practices (in that they own Makerbot, the infringer they bought rather than sued) . Rather than adding new projects to Thingiverse, I'm feeling more inclined to taking my stuff down. If I thought anyone would notice, that is.

Yep, that's a bit rum isn't it. If you really think nobody would notice, then you've got nothing to lose. The problem is that your content then disappears from view and availability, unless you've got a good set of links to it already out there.

Github / bitbucket is the obvious choice of host for source files. Github even has a native STL viewer these days. I don't really bother with thingiverse any more because it's a pain to actually manage versions and stuff on, rather than for any political feelings, but it's been turning a little disingenuous for a while now.

Github seems to index reasonably well through google too, at least if you put a good README.md in the project.

I started going down the Github path, but chickened out halfway through the process. It's just too foreign for a non-programmer like me, and the benefits of version control are outweighed by the learning curve.

So I took the easy course and put the files on YouMagine.com.
https://www.youmagine.com/designs/kongorilla-s-led-light-painting-gondola

Since this project will appeal to only a handful of people, I'm not too concerned about where the files live, and I'll use this opportunity to kick YouMagine's tires. For those interested, the upload process was equivalent to that of Thingiverse, with the annoying exception that images must be 16:9 (landscape) or they will be cropped.

Aye, that's a fair point, Git isn't trivial unless you are a masochist already using it every day. I only mentioned it so I sounded like a pro, now I just seem like a jerk. Good spot on youmagine. What an awful name though?

In a world where a site called "Yahoo!" was trumped by another called "Google", what's in a name? Even so, yeah, "YouMagine" will be tough to say out loud in group situations without some embarrassment. Also, it's as (potentially) partisan as Thingiverse, in that it's Ultimaker's site, but I've got no beef with them.

POSSIBLY IMPORTANT:
It just occurred to me that, I believe, my servo has always rotated counter-wise to the polargraph norm. So, everyone should probably flip the servo from what's shown in my images.
