How to setup openscad and design objects for RepRap printing

We got a reprap! Time to design some stuff in openscad to print. Ongoing post with helpful hints mainly so I can look back and remember how I did something.

Install Openscad

$ sudo add-apt-repository ppa:chrysn/openscad
$ sudo apt-get update
$ sudo apt-get install openscad

sudo apt-get install build-essential git

install slic3r to convert our openscad files to gcode files (what the reprap reads!)

git clone https://github.com/alexrj/Slic3r

cd Slic3r

sudo apt-get install libwx-perl

sudo cpan Build

sudo perl Build.PL

sudo cpan Wx

./slic3r.pl
