foldable notebook stand one piece print

Inspired by the Geometric Adjustable Laptop+ Stand by ConMacDesign (thanks!), I've designed this stand which is foldable, adjustable (4 positions 15°, 25°, 35° and 45°), portable (I put it in my notebook bag) and, moreover, printable in one piece.

It takes 5 hours and 51 minutes on my flashforge dreamer, standard quality.
No need for supports, raft or brim.
No need for screws or nuts, the stand is perfectly working once printed.

In order to have full stability you have to print 2 of them (see pictures).

Feel free to use the model as you want, just let me know if you liked it!
