Plant grow box portable and space-saving dismountable

My girlfriend needed a box with lighting to grow her plants. Preferably with a light that can be adjusted in height. So what else could I do but engineer one?
 

The lights can be moved and their height can be adjusted to suit the plants. I recommend using 2-3 lights for one box. If it's not too dark, two should be enough. We have the boxes with 3 lights in the basement. 

Designed to be printed in PETG or PLA.
For the threaded inserts you should print with 4 perimeters, some parts will need supports.
