Summary

A great bird bath design by Nebojsa that I modified in Orca slicer to go on any flat surface with 2 clips to secure it in windy conditions, the original was designed for a balcony shelf or similar, so it had a lip on the bottom front edge.
Using Orca slicer, I cut the lip off the front, then added 2 primitives (cubes) 2mm high as tabs, then made 2 clips with primitives.
