Inspired by [Blossoming lamp](https://www.thingiverse.com/thing:618490)                  

Print : 1 mount_arduino, 1 opening_platform, 5 opening_lever, 5 opening_intern, 5 opening_fix (+ optionnal : 1 opening_bends) (+/-9h, 65g PLA)

Attach the linear_actuator_attachment to the opening_bottom with a bolt M3x25 and three M3 nuts.                        
Use some threadlocker glue to secure the head of the bold on the yellow part.                       
Screw a nut on the bolt.                       
Then screw the green part on the bold while securing the nuts with your finger.                       
Hot-glue the LED on the center.                       
Attach 6 wooden pike to brake at around 10 cm (depending on the length of the interior of your folding) to the opening_bends or opening_lever
