I present my Disk pendant, for use with nine 2x6mm tritium vials, which are held in slots around the disks inner channel (tritium vials not included).
This model has been scaled for printing in silver, brass or bronze.
The small attachment loop in the top is 2mm in diameter. It is large enough for very fine necklace chains.
This is one of two printed parts needed to complete the assembly. The other part, in frosted detail plastic, can be found here: Disk Pendant: Tritium, Part 2 of 2 (it is not included with this model)
The tritium vials and frosted plastic parts should be set into place, 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.
I have a few tritium lanterns, available from my Etsy shop (tritium vials not included, due to a recent policy change on teh site). Please contact me if you would like an assembled lantern.
There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page.
