3D Ball And Socket Joint

For 3D printing, we are making an action figure that needs to have 9 joints, one of the joints needs to be printed separately and snapped into place. This is my prototype ball and socket joint before making it with the action figure.

Design time: 30min | CAD Software: Fusion 360

Print Software: Cura |Printer: Ultimaker 2+ |Print time: 12 minutes

Instructions:

  • Create tab: Make sphere that is 10mm> create a new body

 

 

 

 

  • Create tab: make a cylinder that has a diameter of 5mm and height of 15mm>join

 

 

 

 

 

 

  • Un- Highlight the newly made sphere and cylinder
  • Create tab: make a sphere that is 11mm>create a new body
  • Un- Highlight the newly made sphere

 

 

 

 

 

  • Create tab: make a sphere that is 12mm>create a new body

 

 

 

 

 

  • Modify tab: target body 11mm sphere clicked and tool body 12mm sphere clicked>cut

 

 

 

 

 

 

  • Create offset plane on X plane -1.50mm distance

 

 

 

 

 

  • Modify tab: split body tool highlight 12mm sphere as a body to split and highlight newly constructed offset plane as the splitting tool.

 

 

 

 

  • Adjacent to newly cut 12mm sphere create a box that is 2mm length by 30.00mm width and extrude height to 10mm>new body

 

 

 

 

 

 

  • Highly newly made rectangle and rotate to make an x (perpendicular)
  • Combine newly made “X” as one body via the modify tab

 

 

 

 

 

 

 

 

 

  • Drag “x” in center of a 12mm sphere, drag to through sphere leaving 75% of sphere out of the “x”. In the modify tap: combine tool, highlight sphere as body and the “X” as tool bodies > cut.

 

 

 

 

 

 

 

  • Create tab: make a cylinder that has a diameter of 5mm and height of 15mm> join

 

 

 

 

 

 

 

  • Create tab: make a sphere that is 11mm inside 12mm sphere to cut rest of cylinder inside the sphere and make it flush> combine to cut feature.
  • Highlight ball and socket bodies and used the create tab to make a new component, label it “ball and socket”.
  • Un highlight ball and socket bodies and the component. Highlight the 10mm sphere body with the cylinder attached to it and use the create tab to make a new component, label it “ball and shaft”.
  • Save the “ball and socket” as one STL file and “the ball and shaft” as another STL file.
