3D printed Wheelchair-Ramp for one step

As a wheelchair-user i often need to overcome a step in front of a building, a shop, cafe or bar. Therefor i had the idea of printing me my own small ramp. It has to be as small as possible to carry it in my bag, when i'm on my way through Berlin.

This is my first prototype. Please feel free to print and to develop it... Any feedback is apreciated!
