I present version 4B of my tritium keychain lantern for use with a 3x22.5mm tritium vial (tritium vial not included).
This model has been scaled for printing in stainless steel and it's variants.
The attachment hole is large enough for paracord, gate clips and split rings of various sizes (not included).
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 printing process some gentle drilling may be required on the tritium vial channel to ensure correct fit.
I have a few assembled tritium lanterns, in stainless steel, silver and bronze, available from my Etsy shop
(tritium vial glued in place with Norland 61 and split ring installed). Please contact me if you would like an assembled lantern that is not present on Etsy.
There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page
