This is rotary electrical connector for transferring electrical current in full 360 circle. It has +,-, and GND connection. Also included in documents 3 drawings for cutting out copper connectors in 1:1 scale. It should work for 6v, 12v and 220v current (tested at 220v). 

ASSEMBLY

  1. 3D print Bottom Part and Cover ( best 0.2mm PETG or ABS)
  2. Print on paper 3 included drawings
  3. Glue drawings on copper sheet and precisely cut out given forms
  4. Bend small ears on each form for 90 in same direction
  5. Cut out 3 pushers (best cut out 3 strips 4mm wide and 13mm long and bend them cca 45 deegres)
  6. Put coils in Bottom Part (put small amount of super glue under them)
  7. Put pushers in Cover part (bended part should sit on 3 half balls so they get pressed all the time)
  8. Connect your wires in order ( biggest coil (+), middle coil(GND), Small Coil (-))
  9. Hole trough Bottom Part is currently diam. 35,2mm but feel free to change size to your central rode or similar.
  10. For best and longest use, put some grease on all plastic and copper parts 
  11. Enjoy your 360 rotary connector

If there will be any problems, feel free to contact me :)

 

P.S. 

Theoretically it should work to transfer communication impulses but not tested. (If you test this kind of connection please leave comment if it works ):)
