I am having a bit of a hard time understanding why the STL export differs from what I see in my model.
Currently I am trying to create a 3D printable mould to create beeswax foundation. I have created a small example of the problem I am facing.
In Blender my model looks perfect, each hex has 3 edges meeting in the center of the cell, the mid point is then moved up 1mm to form the indent in the mould. Here is what it looks like in Blender, you can clearly see the three faces.
You can find my blender file here
Any suggestions welcome.
