TPU shelf corner bumper

When I hit myself in head I decided to print soft bumper for sharp edges of my shelf. I wasn't happy with the designs that were available on Printables so i decided to design my own project from scratch.The main difference is that walls are curved to compensate softness of the material - so the bumper fits into the shelf corner even without gluing (but it's best to add some glue or double sided tape for security).This project file should be printed with soft corner pointing upwards. If you have any adhesion problems - add brim. Use whatever works with your TPU and 3D printer.This piece was designed for 90 degrees corner of 18mm thick shelf.
