About this 3D model

This object was made in Tinkercad. https://www.tinkercad.com/things/2xsME6R34F9 One ending Shell 4 is the Snitch, Shell 3 is the Quaffle. Shells 1 & 2 are Bludgers. I had uploaded them all together from TinkerCAD then an admin separated out the files and I don't know how to rename them without potentially messing up the review process. Submitted for the Pots & Planters Design Challenge.
