So i'm using this trick (since i'm a kid) to have light at 360 degrees when only having a flashlight or smartphone and a bottle of water (transparent). It's perfect for camping, when you want to play cards (while drinking some booze...), in your tent with your wife (or dog for the luckiest) or just for your kids in their room. (I don't have kids, dogs or wife so if they don't like it i'm not responsible)
Anyway i just got my hands on a Flashforge Dreamer and decided to design something light foldable, small enough to fit in my backpack. It can work with every type of phones if it have a flash.
This is my first design so it as some flaws. Only one actually: If you print it you will have to cut the top of the bottom part (not the bottom of the top one!). I had to cut 0.1 mm on each side of the "pins" to make it fit nice and tight (If you know what i mean). I will fix and update it later when i will have more time.
-RAFT : NO NEED
-SUPPORT : NO NEED
-PRINTING TIME : 6-7H in total (a rat ate my filament so had to reload it...)
Layers: 0.2000 mm
-TOP SOLID LAYERS : 3
-BOTTOM SOLID LAYERS : 3
-SHELLS : 4
-INFILL : 15%
ps: I choose wooden filament and a concentric External Fill Patern (I like it this way).
