A christmas tree that is lit up by a small 3mm LED, other hardware is used from a cheap flashlight you can buy at the ACTION. Parts used are the button and the wide spring. 

The pot has a print in place knob in it so te click mechanism looks nice. 

It is a fairly easy thing to put together and it looks fun!

The christmas tree is inspired by: https://www.printables.com/model/91408-vase-mode-christmas-tree , this model. It has to be printed in vase-mode without bottom layers. 

TO ASSEMBLE:

1. Bend the wire from the switch so it faces with the metal plat that is on the switch.
2. Put the switch in place
3. Put the battery in the pot, ‘-’ facing downwards.
4. Bend the top part of the spring where it gets narrow so it fits in the hole from the screw cap
5. Put the screw cap on and make sure the negative wire is fed trough one of the openings that is in the screw cap
6. Tighten the screw cap using the tool wich fits in the 2 rectangular openings. 
7. Put the LED in the LED-HOLDER and bend the wires and cut them to length
8. Put the LED holder with the LED in the openings where you tightend the screw cap with, it is a pressure fit
9. Solder the wires from the LED, one to the spring, the other one to te wire coming out from the switch.
10. Put the christmas tree on the pot and you are done!

NOTE:

• When the pot is printed you will have to push the knob that is printed with it so it can move, there is a clearance of 0.2mm on each side, for me this was enough.
• The flashlight you need is the one in the last picture, it is cheap and where I live easily obtainable.
