This is a collection of 666 Asset Browser ready, curve object, Blender icons.
The base vectors are from an unmaintained collection of Blender's original icons by Shrinks99 (it might not have newer icons after 2021).

You can also get official vectors here https://ui.blender.org/icons, but importing and cleaning up vectors in Blender can be annoying, so I wanted to offer these ready to go.
I cant make products free here yet, but you can support Blender with a dollar, or you can get this on my Gumroad for free.

Blender's icons are released under a CC BY-SA 4.0 license.
