time is pressing.. and i won't get my big pulley-mould printed.
with some try and error it worked with a 112 pulley:

but the 125 pulley that i made exactly like the smaler one is only sliced into big "black" discs:

It is a perfect manifold (strg+shift+alt+M no longer yields any verts)
and i simply don't know what else i can try :'(

my blend file: pulley125b.rar
the stl export of the 125 tooth pulley mould: pulley125b.stl
the gcode file: pulley125b_export.zip

i don't know why slic3r says "The model has overlapping or self-intersecting facets."

dasRoland.de
Ideas welcome :-/

Slicing D:\reprap\pulley\pulley125b.stl
Slicing:  Slic3r/slic3r.exe $s --load Slic3r/config.ini --output $o
=> Processing input file D:\reprap\pulley\pulley125b.stl

=> Processing triangulated mesh

The model has overlapping or self-intersecting facets. I tried to repair it, however you might want to check the results or repair the input file and retry.

=> Generating perimeters

=> Detecting solid surfaces

=> Preparing infill surfaces

=> Cleaning up

=> Detect bridges

=> Cleaning up the perimeters

=> Generating horizontal shells

=> Combining infill

=> Infilling layers

=> Generating skirt

=> Exporting GCODE to D:\reprap\pulley\pulley125b_export.gcode

Done. Process took 1 minutes and 51.406 seconds

Filament required: 49248.1mm (348.1cm3)

49247.13568 mm of filament used in this print

the print goes from 12.739000 mm to 227.379000 mm in X
and is 214.640000 mm wide

the print goes from 12.604000 mm to 227.384000 mm in Y
and is 214.780000 mm wide

the print goes from 0.400000 mm to 22.000000 mm in Z
and is 21.600000 mm high

Estimated duration (pessimistic):  55 layers, 09:10:15

okay, the 112 pulley does not have these "intersecting faces":

some more hours of frustrating blender-work tomorrow..
*good night and good luck*

Okay, i had to "normals - recalculate outside".
So always show the normals before exporting to stl:

I usually use cloud.netfabb.com to check my STL exports.

It's a beautiful design btw! What technique did you use?
