I used a Gridfinity Creator Solid Bin 2x2x3u as a base to recess the new Oura Ring 4 charger and to accommodate the USB-C plug, too.
I use this towards the back end of my nighstand, so I'm fine with the cable hanging out in the back. Depending on how you want to use this, this might block any further bins behind this one.
I used white Bambu Lab PLA Matte and ironed the topmost layer.
