Ben Hargreeves - The Umbrella Academy
This is custom figurine of Ben Hargreeves, a.k.a. Number Six, a.k.a. The Horror from Gerard Way and Gabriel Ba's comic and Netflix TV show.

The tentacles were printed by arranging parts in Cura and then heating them with a heat gun to curve them after printing.
I've included the Blender file as well.
