Customizable general box maker (for drawer)

I was looking for different type of boxes used in drawer or closet. Finally I was inspired by https://www.thingiverse.com/thing:3171891 which is an amazing design almost meet all my demands.

Well I did some small enhancements on top of that:
1. Configurable inner height for the grid wall
2. Configurable having stack w/o supports
3. Enhance the connections between outer wall and the bottom
This is my 1st upload, so please live with that:
- No lid
- No round corner
I may enhance this later.

The STL is just a sample of configuration. For most of the configure instruction, especially the grid part, refer to https://www.thingiverse.com/thing:3171891

Hope you can enjoy my design.
