2. How to install §

Short instructions how to install sheetstruder, I will send some documentation upstream. You need git and python and later you will need openscad and a spreadsheet tool.

git clone https://git.hackers.town/seachaint/sheetstruder.git
cd sheetstruder
python3 -m venv sandbox
. sandbox/bin/activate
python3 -m pip install -r requirements.txt

You will need to be in this shell (you need at least the activate command) to make it work.

3. How to use §

Open a spreadsheet tool that is able to export in format xlsx, type a number to create a solid object of this width (1 = 1 pixel, 2 = 3 pixels because it's mirrored) and put a background color in your cell. Save your file as xlsx.

Run "python3 ./sheetstruder.py yourfile.xlsx > file.scad" and open the file in OpenSCAD, enjoy!

4. Examples §

I made a simple house with grass around, an antenna, cheminey with smoke, a door and window in it.
