Dyne's Treadwell

[Dyne]

I've been using this project to experiment with some of the features of Fusion 360 that I don't normally use (which is a lot of them; it's a big program, and I've only used it off and on since last summer).

Among those features are the drawings I posted before.  The first version of the Overview sheet was literally the first functional drawing I've made in the software. (Speaking of that drawing, in detail A where the Eyelids join the upper and lower wall, there's now a 45 degree slope rather than a ~90 degree angle. That's to avoid the need for support when printing.)

Speaking of drawings, here's another one.  This is the head assembly.  I'm still trying to settle on a workflow for assemblies and better sort out how joints work, but I currently do have the head tilt working.  I've improved my title block since the last drawings, and added the company name in Aurebesh to the logo.



The BOM lists some materials, but those just contain whatever I happened to attach to the parts and are not a true reflection of what I'm using.  If you are wondering what's up with the random fractional measurements, it's because I'm working in millimeters, whereas the original plans in our files were specified in inches ... e.g. the gap between the upper eyelids at grid D2 is 1 inch.  I've tweaked some of them and made up others as needed, so they won't all convert nicely back into inches.  Doesn't matter for my purposes, since I can type them into the software either way and get consistent units in the output, and much of this is going to be printed (probably not in ABS).

As you can see, I recreated the lens and its holder in CAD.  Mostly that's because the STL files were being weird (importing at the wrong size) and were refusing to convert into decent solid models.  I tried to reproduce them as best I could from Savage's originals and the photos.  

Here's an exploded drawing of that.  I didn't bother reproducing the rear half of the little flange because it isn't visible on Treadwell.




Incidentally, the plans already on the site are not quite complete.  In particular, they did not list several dimensions of the eyebox mounts, the angle they should be at, etc.  I just eyeballed it, and went back to reference as needed.  I will probably tweak the design of those parts so they can be printed separately and screwed to the eyebox.  If they were printed as an integral part of the eyebox, they'd need support.


I'm also experimenting with the render feature.  I could also do this in Blender or what-have-you, but it'd be a pain to export all the parts to a useful format, make sure they were assembled correctly, set up materials, etc., just for a still shot.  Luckily, Fusion 360 already had an appropriate environment available...
