Designs Not Printing Correctly

[RobH2]

The important thing but the hardest thing it to figure out where the error is coming from. You need to eliminate as many things as you can and zero in on the issue. If you will upload your model I'll make sure it is a good manifold, meaning, that it's watertight and has no errors. If the model is faulty then you might have your solution. If the model is fine, then you know to look elsewhere.

Im trying to figure out how to upload the model lol. Thats sad I know

Ok figured it out

The mesh has problems. That's not uncommon for SketchUp. It's notorious for "not playing well with others." Let me see if I can get it open and fix it.

Below is the report on the mesh from Rhino3D:

---------------------------------Begin Paste------------------------

This is a bad mesh.

Here is what is wrong with this mesh:
Mesh has 1 degenerate face.
Mesh has 175 non manifold edges.
Mesh has 3 duplicate faces.
Skipping face direction check because of positive non manifold edge count.

Important things to consider with this mesh:
Mesh has 6 naked edges. Although this does not necessarily mean that the mesh is bad,
naked edges can cause problems if the ultimate goal is STL output.
Mesh has 5 pairs of faces that intersect each other. Although this does not
necessarily mean that the mesh is bad, it can cause problems if you're doing mesh boolean operations with it.

General information about this mesh:
Mesh does not have any extremely short edges.
Mesh does not have any disjoint pieces.
Mesh does not have any unused vertices.

Here you go. Try these. Let me know if they help. They are error free.

triple 18650 v3.obj
triple 18650 v3.STL

As for free software, Blender is probably the most powerful but has a steep learning curve. Still, it's really great. There is a CAD program called FreeCAD I think that will do solid modeling. Finally, try Meshmixer. It's a slicer too.

Its perfect! May I ask how you went about fixing it? Im curious that way I know next time
