Hello Inavarro,
sorry that this model caused you problems!
The daily earring projects tend to be sloppy as I did them quickly, usually in the evening, and the UP's software is pretty forgiving. Did you try the file "__THIS_swiss_Leveled_OuterShell.stl" - or which one did you try slicing/printing?
The tool rings should be identical (1mm thick, 4mm diameter, 2mm hole diameter), I do know thing objects like this can behave strangely when printing (+-1 layer rounding or when not level).
The Earring ring is 0,8mm as my fiancee had problems getting the thicker rings through her earrings, at least when painted. It's thickness can either b adjusted in the original sketchup file or check out the non-unified model where you can still resize the ring's thickness.

About th attachement issues, it's a quick and dirty work, some volumes probably still intersect. You can just run it through netfabb or netfabb's online service, or use a 3D suite of your choice to unify the model.

Good luck! :-)

When I slice it, the rings for the blade and for the cover aren't actually attached to the blade or the cover, and I don't know how to fix this…. it's probably maker ware's problem though.

the knife's ring seems to be much more delicate than the bottle opener's ring….

Glue carefully, it's tiny! :-)
Use instant glue and move the blades for a while so they won't stick.

ToDo:
-Coloring
-Add stoppers to limit turning

Are the blades supposed to be hovering like that in midair?

Sorry about the bad pictures, but the blades attach to the axes and are then movable.

-The color rendering shows the assembled version with the blades out and in.

-The STL contains the parts seperate in order to print them on a FDM machine, it might be possible to print the whole thing in one piece via SLS if the gap tolerances are fine enough.

On the photo you can see the assembled (uncolored) prototype with the blade and can opener turned into a random position and the swiss cross upwards.
There is no limit for the blades yet (a little difficult to print at this scale) so the blades will turn all the way. This can be fixed by either making the sides a bit thicker and adding a pin to block the movement, or simply glue in a little wire or scrap piece of plastic.
Most earrings I make just need to be decorative and have limited functionality, like the working pad lock, which has no "real" locking mechanism but a simple construction that somewhat simulates this functionality.
