Printed in PETG in various colors , some parts 0.3mm layer to reduce time ,hands 0.2mm layer, all parts without supports .

The link between petals are printed using Tansparent Petg , needed to avoid petal movements

The total width of the clock is about 70cm

The total print time is around 60 hours  

Clock mechanics used :  JUNGHANS W838 or UTS 800 ,  axle length 16mm

Made on my Prusa MK3S+ 

Happy printing :)

As requested , here the instructions :

 1) print the clock body  
    black color,  no supports , PETG , 0.3mm layer, infill 10%
 

 2) print 4 main petals , for 3, 6,  9 and 12 o'clock
    strong colors , infill 0%, PETG, NO SOLID layer on top , NO SOLID layer on bottom 
     take attention to place in the clock body slot ,  the 12 o'clock is placed over the clock hook !
    ( I choose the color blue and red )
 

 3)  print the remain 20 petals and place them in the slot  (see image) 
 

4) print twice the hour_placeholder.3mf to obtain 12xHour Placeholder 
      PETG , white color 
     put them in the petals . The rear view is shown in the image  

5) print twice the link.3mf to obtain 24xLink 
   PETG Transparent ( to stay hidden )
   this part  is mounted in the back side , necessary to block each petal, this avoids the oscillations 
   (see the image )

6) Print the hands and mount the clock mechanics as indicated by the mechanics manufacturer
