I love the box by MrElektro@MrElektro_32607 . I wanted to create different size boxes and also wanted a stackable version. I've not had much luck editing and scaling .step files . I'm also concerned that things like wall thickness won't scale well.

Features:

• Fully Paramteric - just tell OpenScad the Height, Width and Depth
• Option for a stacking version
• Option for Voronoi patttern
• Option for hex pattern

Using OpenSCAD 

• download OpenSCAD  [https://openscad.org/downloads.html](https://openscad.org/downloads.html)
• open the  .scad file  
• make any changes you need
• Use F5 to preview the model or via the menu Design/Preview 
• Once you are happy with the model use F6 to Render the model or via the menu Design/Render 
• Use F7 to Export the STL or via the menu File/Export/STL

You can find shortcuts for preview, render and STL on the menu bar 

Customising the Model

• Choose either the sloted, hex or Voronoi version
• If you need to understand  the OpenSCAD language start here with the Cheat Sheet 
• In the OpenSCAD file find these lines and change as needed

         wallthickness = 3; // Wall Thickness

          box_height = 50; // Height of the Box
           box_width = 140; // Width of the Box
           box_depth = 80; // Depth of the Box
           box_radius = 5; // Radius of the rounded corners

• Rendering ( see F6 above ) takes about 20 seconds on a Mac. Beware large Voronoi boxes can take a few miniutes to render.
• To print you export the STL from OpenSCAD and the slice it.

Voronoi version

There are options in the Voronoi version to use the same pattern on all sides or to use a random pattern. I suggest you start with the standard setup. Voronoi starts to take a long time to render when you increase the size and or number of patterns. So start simple and go from there.

Hex Version

Use the openSCAD files in the Storage Box Hex Folder

33 Pattern Version

This option is a bit more expeimental. But there some really nice patterns.

It uses a openSCAD file from [https://tecnoloxia.org/100hex](https://tecnoloxia.org/100hex) . Some of the patterns are not working ( see comments in  hexpattern.scad ) . Suggest you enable fast-csg in the  openSCAD Preferences.

To use

1. Load both the Storage Box Patterned and hexpattern file from the Storage Box Pattern Folder
2. Set the pattern number e.g. pattern = 1; in hexpattern.scad - Important save the file
3. Switch to the Storage Box Patterned.scad file render and export the STL

Note if you get the error WARNING: No top level geometry to render its because you tried to render the include file hexpattern.scad . You need to render Storage Box Patterned.scad 

Printing

I used 

• PLA 15% infill. 
• 0.20mm Speed
• Printed  with the base on the build plate
• Supports - Build plate support for the stackable version otherwise no supports.
