The original Pixel 6a by @Engine_Jam_588019 was just what I was looking for but
I was concerned about the microphone hole being largely blocked.
I used PrusaSlicer's negative volume feature to expand the opening a bit.
Printed in SainSmart TPU with supports everywhere. TPU is a pain with supports!
The author remixed this model.
