Sensor holder for the new Freestyle Libre 3 CGM sensor. It has slightly different dimensions than the Libre 2.

I printed it in TPU 95A for a smooth feeling and in PLA because my wife said, it's okay to wear the PLA version.

You will need some kinesio tape to fix it. You can find a template for the kinesio tape here:
