How to prevent hidden shapes from being exported to .stl file? I've created a replacement radiator knob in blender to get it 3d printed.
I've used array modifiers to replicate shapes mirrored around the center.
And I have used a Boolean modifier to create the notches for more grip.
The problem is that when I export to a .stl file the shapes that I have hidden use the &quot;eye&quot;-buttons also appear.
How can I remove them when exporting?
What it is supposed to look like after exporting:

What is looks like after exporting:
Before exporting, press A in object mode to select everything, this won't select any hidden object.
Then while exporting, check &quot;Selection Only&quot; on the right to export only the selected objects.
