How to fix shoes with 3D printing - the fight against the world wide waste

In 2022, 23,9 billion pairs of shoes were manufactured worldwide. That is equivalent to 757 pairs of shoes every second! Lets fight against the world wide waste and give our shoes a second chance! So I tried to fix a hole in my shoe soles with 3D printing to extend their life span as long as possible.
