Speaker Suspension from Ceiling

For one complete speaker suspension you need:

[A] Printed parts
  A.1     1x Aufhaengung_Box_HalterDecke_bajonett_male_v01
  A.2     1x Aufhaengung_Box_HalterDecke_bajonett_female_v01_3
  A.3     1x Aufhaengung_Box_TeilDecke_v00
  A.4     1x Aufhaengung_Box_TeilBox_v00
  A.5     8x Aufhaengung_Box_Spacer_v00prt_1

[B] Additional parts
  B.1    4x M3x25 screw (Hex socket head)
  B2    4x tension spring l=32mm, diameter=6.5mm, D≥3.5N/cm

Printing:
3d-parts can be printed without supports.
PET (or stronger) recommended.

Assembly:
[1] Assemble suspension with parts A.2, A.3, A.4, A.5, B.1, B.2

[2] Attach A.4 to speaker with 4 4.0x20mm screws (SPAX)
      Center the part (left/right)
      The distance from the back side influences the vertical tilt of the speaker.
      (I measured the center of gravity of the speaker and positioned A.4 in such 
        a distance from the back wall, that a tilt of 20° resulted)
      → this needs to be evaluated for each type of speaker

[3] Attach A.1 to the ceiling (with 2 4.0x<lenght>mm screws / SPAX)
      - holes spaced 45mm apart
      - make sure the fixation can carry the weight of the speaker + cable

[4] Mount the speaker by locking A.2 on part A.1 (insert bayonet and turn clockwise)
      while holding the speaker in position.
      Hint: Connect speaker cable before mounting.
     ATTENTION: The bayonet is not secured mechanically!
                              Make sure you do not accidentally unlock without holding the speaker!

[5] Adjust horizontal orientation of speaker by rotating A.3 accordingly.
      ATTENTION: Hold A.2 in locked position to avoid accidental bayonet unlocking.
