About this 3D model

One of my first designs. This was made for a puzzle cube project. This is designed to hold a volume of 2.3" x 2.3" x 2.3" Total Diameter of each part is 4" The files come without the logo, But you can add your own if you want. I have printed this with a Makerbot Replicator (5th Gen) This was printed with a raft and supports. But I dont think it needs a raft.
