Learning some OpenSCAD by building up some models and libraries. So far this is entirely intended for 3d printing.
In OpensSCAD, go to Help -> Library Info and look for "OpenSCAD library path". You'll see something like ~/.local/share/OpenSCAD/libraries. Inside there, clone BOSL2 and also link to the lib directory contained in this repo, if needed.
mkdir -p ~/.local/share/OpenSCAD/libraries
cd ~/.local/share/OpenSCAD/libraries
git clone git@github.com:BelfrySCAD/BOSL2.git
ln -s ~/dev/printing/lib don
