In this picture the phosphorus coating on the tritium vial being energised by UV light.
I present my 'Tardis' styled tritium lantern for use with two 3x22.5mm tritium vials (tritium vials not included).
This model has been scaled for printing in stainless steel.
The attachment hole is 3x3.5mm wide and is perfect for a length of paracord or a large diameter split ring.
The tritium vial 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.
Due to potential irregularities in the stainless steel printing process some drilling may be required on the tritium vial channels to ensure a correct fit.
I have a few assembled tritium lanterns in stainless steel available from my Etsy shop
(tritium vial glued in place with Norland 61 and split ring installed).
There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page
