The AirPods sound OK by themselves but sound much better when pushed into your ear canal. I want to try one of the silicone sleeves but they obviously don’t fit into the case. I’m wondering if there is an easy (relatively speaking) way to remove the lid and replace it with one that would accommodate the larger profile. It would be nice to see some photos with a little more detail of the hinge mechanism. Has anyone built an accurate 3D model of the case? A surface model is probably good enough to work with.
