Small pedal shaped tritium vial holding decorative bead with large side cut-outs, designed to take two of the 2.5x10mm tritium vials (tritium vials not included).
This model is sized for printing in stainless steel, for the model sized for printing in sterling silver or one of the various plastics available please check my shop.
The central hole is 5mm in diameter and should just be wide enough for two lengths of 550 paracord.
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.
There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page
