Sample HiRes STL output file

Hi Guys:
For those of you that do 3d printing, Im posting this sample output from Gearotic Thoughts. Its the new helical
output, ( with spokes ) and in hi-res closed manifold form. Im interested if any of your 3d printing software likes
it or doesnt like it for some reason. It should be accepted easily, though it is about 12 megs in size because its
put out in ascii format. Also, Id like any feedback on if you can use binary stl's or not, if its a common thing
that your importer allows binary, Ill also add binary output from GT.
Thx
Art

I tried Rhino 4, Rhino 5, ArtCam, Autodesk Inventor Fusion, Solidworks & DeskProto 6
nothing works to import the stl file

netfab studio and slic3r don't like either

Wow.. and yet I can load it and Asimp can.. lol.. better broaden my test runs.. I may have uploaded a
defective too, Ill update you shortly.. Thx for the test.

On import it crashes OneCNC XR5 as well.

Assimp is a 3d file translator/viewer. I used it to test my stl. Both GT and assimp loaded it fine, so I jumped the gun.
Ive just replaced the file in the original post with a new one, without the export typo's causing failure on most programs.
Ive tested this one in multiple stl viewers.. Bad news is Im still having trouble getting slicr to load it. It loads fine then slicer bugs out.
Im thinking it may be memory in slicer.. anyone know the limit on it? The helical is about 250,000 vertices. ( pretty high res, I notice
slicer has troubles with many samples Ive downloaded as well.
Anyone use slicer alot? Does it fail on large files? ( Am I really going to have to add slicing capability to GT to compensate for that? )
Please try the updated file and let me know how it does on your system. Vectric Cut3d, assimp, GLC_player have all loaded it fine
so far.
Thx , sorry for the buggy first one..

Ken:
Thx. Its good to figure this stuff out early on. Most file formats have their up's and downs. STL is really a bad format, it has mutiple vertices in it instead of
indices tables. Coudl be much more efficient really..
I think I have it right now though, it was just a typo in the ouput code, rather simple format to do really. Only the question is, why doesnt slicer load it?
Ill have to experiment, but Im thinking it may be the size is just too large, though that seems funny, its not that big. I plan on allowing a single STL output
of entire mechanisms, so the triangle count would be in the millions. Im hopeing general 3d printing software will allow such large files. I should have my
printer around the end of the month to use in testing, so Ill know better then I guess.
Thx fer the test

new file loaded into netfabb studio ok,
as you say it crashes slic3r i used netfabb to save it as a binary stl , which again crashed slic3r
the beta version of the latest slic3r (9.02 i think) accepted both versions happily , i did not try to print it as the resultant gcode looked a bit too small to be valid .
do you really need that sort of resolution / can a 3d printer really resolve that much detail anyway
