Assembly
 

Step 1:

(Parts needed: Tannenbaum_Stamm + Tannenbaum_Stamm_Bottom + Tannenbaum_Stopper_Bottom ( x 2 ))

• (Do this step or the Tannenbaum_Stopper_Bottom first, whatever you prefer.)
  
  Gently screw the two parts (Tannenbaum_Stamm + Tannenbaum_Stamm_Bottom) together:
  
  (Be careful, all threads can easily break by twisting too hard! Make sure that the threads are clean and there is no support material left.)
   

When the parts are screwed together, the slit on the Tannenbaum_Stamm_Bottom should be aligned with the slots for the Tannenbaum_Stopper.

 

• Slide (and glue) the two Tannenbaum_Stopper_Bottom pieces into place:

→ Tannenbaum_Stamm_Assembly

Step 2:

(Parts needed: Tannenbaum_Stamm_Assembly + Tannenbaum_Stern_Bottom + Tannenbaum_Stopper_Top ( x 2 ))

• Carefully fit the two parts (Tannenbaum_Stamm_Assembly + Tannenbaum_Stern_Bottom) together:

• Slide (and glue) the two Tannenbaum_Stopper_Top pieces into place:

→ Tannenbaum_Stamm_Assembly_Bottom

Step 3:

(Parts needed: Tannenbaum_Stamm_Assembly_Bottom + Tannenbaum_Stern_Mid + Tannenbaum_Stern_Top)

• Carefully screw the two parts (Tannenbaum_Stern_Mid + Tannenbaum_Stern_Top) together:

• Screw the assembled (Tannenbaum_Stern_Mid + Tannenbaum_Stern_Top) to the Tannenbaum_Stamm_Assembly_Bottom:

→ Tannenbaum___Assembly_Bottom

Step 4:

(Parts needed: Tannenbaum___Assembly_Bottom + Tannenbaum_Stamm_Mid)

• Gently put (and glue) the two parts (Tannenbaum_Stamm_Mid and Tannenbaum___Assembly_Bottom) together:

(Make sure everything is able to move! If the threads unscrew by turning, glue them in place.)

→ Tannenbaum___Assembly_Mid

Step 5:

(Parts needed: Tannenbaum___Assembly_Mid + Tannenbaum_Joints + Tannenbaum_Ast ( x 6 ))

• Carefully slide the parts (Tannenbaum_Joints + Tannenbaum_Ast ( x 6 )) together:

• Slide the assembled (Tannenbaum_Joints + Tannenbaum_Ast) onto the Tannenbaum___Assembly_Mid:
  (Lift the Tannenbaum_Stern_Bottom slightly to position the Tannenbaum_Ast underneath.)

→ Tannenbaum___Assembly_Ast

Step 6:

(Parts needed: Tannenbaum___Assembly_Ast + Tannenbaum_Stamm_Top + Tannenbaum_Container_Bottom ( x 6 ) + Tannenbaum_Container_Top ( x 6 ))

• Carefully slide the parts (Tannenbaum_Container_Bottom + Tannenbaum___Assembly_Ast) together:

• Carefully screw the parts (Tannenbaum_Stamm_Top + Tannenbaum___Assembly_Ast) together:

• Then slide the Tannenbaum_Container_Top onto the assembled (Tannenbaum_Stamm_Top + Tannenbaum___Assembly_Ast):

→ Tannenbaum___Assembly_Container

Step 7:

(Parts needed: Tannenbaum___Assembly_Container + Tannenbaum_Stern)

• Carefully screw the parts (Tannenbaum___Assembly_Container + Tannenbaum_Stern) together:

→ Tannenbaum___Assembly_Stern

Step 8:

(Parts needed: Tannenbaum_Layer_Bottom ( x 6 ) + Tannenbaum_Layer_Mid ( x 6 ) + Tannenbaum_Layer_Top ( x 6 ))

• Glue the parts (Tannenbaum_Layer_Bottom ( x 1 ) + Tannenbaum_Layer_Mid ( x 1 ) + Tannenbaum_Layer_Top ( x 1 )) together:

→ Tannenbaum__Layers ( x 6 )

Step 9:

(Parts needed: Tannenbaum__Layers ( x 6 ) + Tannenbaum___Assembly_Stern)

• Glue the parts (Tannenbaum__Layers + Tannenbaum___Assembly_Stern) together:

→ Tannenbaum_assembled

Step 10:

Fill your Christmas tree.

Thank you, happy printing and Merry Christmas! :-)

Instructions

Opening: 

Turn the Christmas star counterclockwise. Carefully pull it up. 
The Christmas tree unfolds easily.

Closing:  ( I'm working on a better closing mechanism )

Gently push the Christmas star down, hold it with one hand. Then grab around the top pieces with your other hand. Lift the star a tiny bit up and push the top pieces under the Christmas star. 
 

To lock, push the Christmas star down and turn it clockwise.
