Fusion Generator / Reactor?
That looks cool will have to find time to print it if I can.
I'm having difficulty with the fit of the parts.  I knew I'd have kerf from the laser, but I measured my as-cut part against the PDF and my "louver ring" (J) lost only .17mm on each side, which is about what I'd expect.  Nowhere near enough to be interesting.  

However when I try to put the grill (I) on the tabs, the slots on the grill are way too close.  If I force them, then the other end bends.

Savage said he cut his from the DXF files and then exported the PDFs, so my wild guess would be that the PDF's were scaled a little when exporting.  (That's a common issue we have with the laser cutters).  My measurements match the PDF's, so I don't think the scaling happened on my end.

The parts that "don't fit" are all on different sheets.  Eg: the brackets (B) are a little small for the base (A).  Brackets are on sheet 02, base is on sheet 01.  And the grill (I) is too small for the rings.  The rings are on sheet 02, the grill is sheet 00.

Not blaming Savage, these things are tough, but I think we need more beta testing!

(I'll post some dimensions in a minute, and Savage can compare against the original)
I'll have a look at it this weekend and see what I can figure out. I didn't have these fitting problems on the one I built, so you're probably right, it's some sort of a file conversion problem
Well, I made a picture of what the old bad scale (red lines) and correct scale (black lines) parts looked like: [Image: normal_Bad_Sizes.png]
As you can see, the first 2 sheets aren't too bad, which would make it pretty hard to notice the error.  The last sheet is quite a bit too large though.

I have no clue how they ended up with these particular scales. My original theory is that they were scaled to fit the available output, but none of the dimensions match the expected paper size, and the last one is bigger than the nominal paper, so that pretty much kills that theory.
Any progress on the files or measurements or PDF scale?
I've posted updated PDFs from Savage's original source.

These supersede the originally uploaded PDFs and have 100mm and 4" calibration scales on them so that people can ensure they're getting the right scale in their output.

These are Savage's files merely re-exported at 1:1 scale.  He intended them for CnC machines and the PDFs are 24x34" sheets.  I haven't updated my laser-cut versions yet.

They also have a small label, so you can tell if it's the corrected file by looking for the scale and label.
Thanks kresty!!
