HELP, Issue with STL not displaying

[VanishedKnight 0]

Hello Guy,

I'm still a novice and I don't know what I'm doing wrong. I made a simple model in blender, it's supposed to be a cover for my changing mouse pad so I can put my larger traditional one on top of it. Whenever I try to export it as an SLT and load it into Cura no geometry displays. From my research I'm assuming that my geometry is non-manifoldasum or something but even after installing blenders 3D paint toolbox it tells me the everything is fine.

I'll proved both the STL and my blender file but could someone tell me what I might have done wrong or if I need to do something specific.
Any help will be greatly appreciate the lads :)

Still having issues but I fix my model and applied the Booleans

Your first model was sort of a mess.  It consisted of 10 separate "meshes" and 7 of them were infinitesimal.  I am assuming that you had not done the Subtractions and Merges.

The second STL you posted looks good and sliced for me.  It's very small though.  Even scaled up 10,000 times it's still just 31.75 x 45.72mm.  That's about 1 1/4" by 1 3/4 inches.

Yes, so the first one was rough I had tried using booleans in blender to subtract the specific dimensions out of a rectangle. I don't know what infinitesimals are but I did see that my method left me with overlapping sects of edges and vertices, which I was able to clean up.

 

I think the final issue is like you said is scale and I believe it's because working in blenders the default unities are m and not mm, not to mention I was translating all my units for inchs into meters. All to say I didn't export it properly in mm so the stl didn't have the right measurements 

Thanks for the analysis :)

Infinitesimal means really, really, really small.  Cura could only describe 5 of the sub-models as 0 x 0 x 0.  They must have some dimension or they would not have registered on the build plate at all.

 

My calculator is always within an arms reach.  I've had the same one for over 40 years.  They still make it, but it's gone from $12 to $150.  Amazing.
