During the period between 2011 and 2013 I have been selling security doors and this repository includes some of the models that I have created in blender both as marketing material and also as drawings that we would then send to the factory to manufacture the doors. Imagine that, I'm just a programmer and I would design a door in blender and then it would end up in someones doorway. Luckily I did not have to build the product myself because that would have been a disaster :-). It was a business I started because I thought it was a good idea at the time. I was really excited about it.
I hated it more over the years though because I did not have time to do programming and had to sell doors instead. So I actually ended up doing OpenERP coding, website development and 3d modelling during that time which were the tasks I enjoyed most with that business. Eventually I just realized that it was a completely wrong type of business for me and let it go.
Some of the media I created during that time is still around though.
