Good design. There is one problem, though: when removing the support, I managed to break off one of the segments. This is partly my fault, but at the same time I have three suggestions for improval: 1) The vertical wall could be 0.5-1.0 mm stronger. 2.) A different kind of (tree?) support would make the model easier to clean. 3.) Also, by using chamfer at the top, there would be no need for support at all.

nice, support super easy to remove. my kid likes uses it for his wired inears
