I present the Ring IX; designed to hold five 2x6mm tritium vials (not included) in cavities across the ring's face.
This model has been designed for printing in either silver, brass, bronze, or gold if you're feeling adventurous, but as the title suggests; Silver was the material i had in mind when designing it.
The sizing of this ring model is 18.5mm internal diameter, a UK Q 1/2 (US 8.5).
The design can be scaled up indefinitely, but any scaled down may require the loosing of a tritium vial, to keep the overall shape of the ring.
If you would like a specific size then please send me a message or post the request below.
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.
The ring in the pictures has had it's vials completely potted using Norland, with the adhesive being flush with the outer profile of the ring, giving excellent protection to the vials from impacts.
