3D Hinge 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 hinge joint before making it with the action figure.

Instructions:

  • Create tab: Make cylinder diameter 9mm and length of 15mm
  • Sketch on plane inside of cylinder a center circle with 7mm diameter, exclude this circle inside the 10mm diameter cylinder at a height of 15mm.
  • Modify tab: highlight each piece separately and combine to cut.
  • Unhighlight newly cut cylinder body
  • Create tab: make new cylinder to fit inside the existing cut 9mm cylinder , use sketch center circle with a diameter of 6mm and extrude 20mm in height.
  • Highlight the previously cut 9mm diameter cylinder and move 5 mm up the 9mm diameter cylinder , in my case 5mm on the Y plane.
  • Highlight both bodies and rotate 90 degrees, so they are flat on the x plane, then move bodies to center axis.
  • Make offset plane 7mm from center.

 

 

 

 

 

  • Create rectangle on the Y plane measuring 4×2 and extrude by 3mm. Make a copy of this rectangle and move it down the cylinder 18mm in the X direction.

 

 

 

 

 

 

  • Using the revolve tool, highlight the face of one rectangle and revolve 180 degrees around y axis, this is also where you select the offset plane made previously.
  • Highlight new body and save STL file at “hinge joint”.
