8-axis Cube Core (assembly)

Description

<I>Note: This Thing Is Not A Complete Puzzle, This Is Just A Core</I> <H1>Description</H1> I Needed A 8-Axis Core For My Redi Cube Clone. Usually 3D Printed Cores Do Not Provide Enough Strenght And Tend To Crack On Layers. I Searched For A Simple Design (At Least Simple For Printing), That Is Strong Enough And Also Provide A Way To Tune Tensioning. Here It Is. Pros: - Uses Regular Rubik'S Cube Core, Screws And Springs - Easy For Printing - All Springs Mechanism Is Located Inside The Core. Attached Parts Require Only A Space For A Nut Cons: - This Design Does Not Fix Axis Orientation - It May Slightly Move Under External Force. This May Be Ok For Some Puzzles (E.G. Face Turning Octahedron), But Redi Cube Gets Too Loose Core Diameter Is 44Mm Materials Needed: - Standard Rubik'S Cube Core - 6X Sets Of Screws And Springs - 8X M3 12Mm Screws <H1>Printing And Assembly</H1> Print The Following Number Of Parts: - 6X Cap - 6X Cap Base - 8X Corner Cap Base Shall Be Glued To The Cap (This Basically Is A Single Part, Split To Simplify Printing). I Used Acethone For Parts Printed In Abs. Use 3Mm Drill To Remove A Small Membrane In Cap Pieces (It Was Designed To Simplificaty Printing And Avoiding Supports) Use Springs When Screwing Cap Pieces To Core Corner Piece Of The Core Is Screwed To Corresponding Puzzle Part (Redi Cube Corner Or Face Turning Octahedron Center Piece). No Need For Springs Here. Do Not Screw Parts Too Tight - It Should Freely Rotate Corner Pieces Have Protrusions That Should Fit Corresponding Gaps In Cap Piece. This Is Done To Fix Piece Position, But Allow Some Elastic Movements Feel Free To Review My Design Source In Details At Https://Cad.Onshape.Com/Documents/0C898146Eff8A4Ab038C2C37/V/965C9B87C16Fa7Cf4B113B59/E/A97D32A0Ffa55F3F443A0366
