Problems exporting 3d layer to stl

[Margaret5EAC]

I am trying to export a 3d layer (see attacked) to .stl for import into Prusa Slicer. I'll then print to my Prusa MK3s printer.

When I export the layer, it exports as .stl (I also tried .obj), but when I open the file in Prusa Slicer, it says the file is empty.

When I export the layer/scene/environment (I've tried them all), I do see a small yellow triangle, indicating an error (I think), but it does not give me an other errors.

I drew this in Photoshop, cut out the slots, and extruded it, all in Photoshop. This is a pickle ball ornament, BTW. 🙂

Photoshop CC 22 on a Windows box.

What am I doing wrong?

Have you tried importing the file back to Photoshop using 3D >New 3D layer from file? That should show you whether the file will re-import and has any content.

The yellow triangle just warns that the file may not print correctly. Try using 3D Unify for 3D printing before export

Dave - Never even thought of that.  When I did that I received an error about UV issues.  So I did a 3D->Generate UV, then 3D->Unify Scene for 3D Printing and was able to bring it into Prusa Slicer and am printing it now.  I did try just the 3d->Unify Scene and it did not work, so the Generate UV was the key. 

Thanks for the hint about importing the file back to Photoshop!
