Thank you for sharing this model. I encountered some issues with printing the label and thought adding a fourth layer might improve it. After modifying the Fusion 360 model to include this layer and a chamfer beneath the label for better print support, I discovered and re-enabled a previously disabled feature that added mid-support to the label, which was very helpful. I also adjusted the scoop profile, which wasn't functioning well for 2U boxes or smaller, and resolved issues with the label supports at these sizes.
There's still an unresolved issue mentioned in your description, but it's manageable with the workaround.
I learned a lot and really enjoyed refining your model!
