Split a large STL file into segments that can be printed separately.

Create your own wall art from an svg file.

You may also need to clean up your files to make sure that they will render in Openscad.

Obviously when making wall art, make sure that the lines are all connected to each other, or the border. You don't want "hanging" artifacts.

The included split-it.json file contains presets to demonstrate cutting up an STL file "test stl", creating wall art "test svg" and using the script to export test.svg "export"

Using the "File" tab

• select the file and scale, move or rotate as needed
• Make sure the entire file is in the positive quadrant (All x, Y & Z values are positive)
  i.e. On or above the Z Axis (Positive)
  On or behind the Y Axis (Positive)

Note: Any negative X, Y or Z will be cropped.

Using the "Bed/Box" tab

• define the cube Size and number of cubed you want to split the file into.
  if you are creating wall art and the image protrudes above the border, drop the height of the cube (Z)e

On the "Border" tab
Select "none" unless you are creating Wall Art and set the other parameter to suit
Note: This will ONLY create a border on the bed.

On the "Preview or Export" tab

• Set Preview or export to "preview" while you are setting things up. In this mode the parameters other than preview line thickness are ignored. In this mode, the entire file and cubes are displayed in their full glory.

You can either export using a script ("export-all.bat" or similar script) or export each cube manually.

Manual export

• Preview or export is set to "export"
• manual export is set to "yes"
• Adjust export cube X,Y,Z to suit
• a preview of the cube will be presented on Openscad
• Render (f6) and export as stl (f7)
• Run through all the cubes THAT HAVE ANY CONTENT until you are done.

Script export

• You MUST have a settings file called split-it.json and this MUST include a parameter set called "export". To sort this put, simply add a preset named "export" and save it.
• Make sure that manual export is set to
  "no" and
• Preview or export is set to "export"
• Exported files are named X-Y-Z.stl and will end up in the same folder the script is run in.

Note: if manual export is set to "no" NOTHING will preview in Openscad
