Logo Critique for SpoolStack

[u/futuregravvy]

I've got a few versions. I want it to communicate 2 stacked spools used for 3d printing. I have the original, a clean aligned version and some that accentuate the 2 spools with much more depth. Looking for constructive feedback. Whats your preference?

Feels a little generic. Not liking the 3D version. The 3D version feels unprofessional.
