These tags were designed for self-made advent calendars, but might be applicable to other purposes as well. The commented OpenSCAD file is provided for customization. Furthermore, pre-rendered STLs for printing in 1-4 colors are provided. My advent calendar usually contains 24 bags, so this is what the main files contain. An additional singular no. 25 is provided, as well.
The pre-rendered tags have an outer diameter of 30 mm (not including the eye) and a thickness of 1.6 mm.
I printed my tags in silver Prusa PLA and in Vanilla White Prusament PLA and they printed fine without supports.
