Small tritium vial holding decorative bead, designed to take six of the 1.55x5mm tritium vials (tritium vials not included).
This model is sized for printing in either sterling silver, brass or one of the various plastics available, for the model sized for printing in stainless steel please check my shop.
The central pin is 4mm in diameter and 6mm long.
The tritium vials should be set using a UV activated optically clear adhesive such as Norland 61 or Loctite glass bond. These adhesives will cure in direct sunlight in an hour or so.
There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page
