This is a thin / low profile case and lid for your standard NTAG 215 25mm NFC stickers. This works perfectly if you need to put your tags on metal. Print at 100% infill. Simply put the sticker inside and put the lid on (and a drop of superglue, if needed). Attach the case to the wall with double sided-tape or a Velcro dot.
