I have been collecting toilet rolls for 4 years with no goal (about 70 rolls, I need to run some statistic to see my daily consumption )
When I have wondered what can I do with that, I rapidly thought to a hip 60′s lampshade. As an engineer, I need some nerd calculations and design
Obviously, I have made a geodesic sphere optimising the roll quantity I get.
