Hi, unfortunately I no longer publish designs on Thingiverse. But feel free to have a look at my profile at Printabled.com: https://www.printables.com/de/social/335893-starwhooper/about

There I will continue to maintain my designs and also publish completely new ones. I have also published several of my designs there in file format for OpenSCAD. This allows you to adapt them better to your personal needs.

Since the original square key for my inspection flaps broke in the basement, I thought about this better design myself.
