I present version 2A 'Paracord' of my keychain tritium lantern for use with a 3x22.5mm tritium vial (tritium vial not included) and does not require a clear tube like my first version.
This model has been scaled for printing in plastic, brass, bronze or silver.
The attachment hole is 3x4mm wide and is perfect for a length of paracord or a large diameter split ring.
This larger attachment hole can be added to any of my other designs of lantern and in any other material, if this is something you might require please contact me.
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.
There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page
