I present version 2A of my tritium keychain lantern for use with a 3x22.5mm tritium vial (tritium vial not included) and does not require a clear tube like my first version.

The attachment hole is 2mm wide and is perfect for a 10mm split ring (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.

I have a few assembled tritium lanterns in stainless steel available from my Etsy shop (tritium vial glued in place with Norland 61 and split ring installed).

There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page.

@gateman42 I have just uploaded a paracord version of the Tritium Lantern 2 in stainless steel: If you would like the same mounting hole on any other lantern design or in any other material please let me know.

@Tofty I didn't mean just the glossy silver one, I meant all of them. I was just a thought. I want a stainless one. Sorry if I caused confusion.

@gateman42 Of course, i'll get it sorted in the next couple of days.

Hey, Can you get the hole a bit bigger, like for paracord?

@Supergome Glad you like the tritium lantern, i hadn't thought of using clear silicone to secure the vial but sounds like a good solution. I've seen a few silver objects finished with the premium polish and it seemed like they got to every surface, even recessed and hard to reach ones. However i prefer the two tone look of the glossy finish with the less polished inner surfaces. After recently learning more about it's limitations i have made both this design and the 'Tritium Lantern 1' design available to print in the stainless steel material. However since they need to be a slightly different size i have uploaded them as different models which can be found in my shop or designer page. Cheers

It took some time to get find a source for the tritium vial, but I love the look of this in Silver Glossy on my keychain. The polish job was fine for me, especially for something that will be in contact with keys, etc. All the exterior surfaces had a good polish, all the interior surfaces were untouched. Looking forward to seeing the effect as the interior surfaces tarnish and the exterior wears. Not sure how much better job they'd be able to do with the more expensive silver finishes due to the shape and size of the product. I think it'd be very difficult to polish any of the interior surfaces. I held my vial in place with a dab of clear silicone at each end, almost invisible and slightly shock-absorbing. Would love to see a model suitable for printing in stainless to reduce cost.
