I only very slightly altered the design from EnginEli.

I was interested in the vase mode for this design, but some areas of the design was requiring some support. And support is not compatible with vase mode.

Speed was my first motivation : more than 10 hours to print a 130x130x110 mm stackable box was not ok for me (why bother printing when you can buy a better product...). 3D printing main asset is versatility...

So i first tried to make the initial design with thinner walls, hoping to cut the printing time.

But it wasn't enough.

So i tried to alter areas requiring support so they could be printed without support for vase mode. (but i forgot some areas... and to my big surprise, the print wasn't so bad, only, these areas are very fragile...). And my gf, didn't like the outcome... the altered design for vase mode is definitely not good enough. (my fault)

Print time for a stackable box 130x130x110 : about 4 hours.

But my alteration of the design is really flawed : not to be used !!!
