This printable ring includes little cut out sections to insert tritium vials - tiny glass tubes containing radioactive gas which glows like a glowstick for decades! They're perfectly safe, but do try not to smash them. A blob of clear nailpolish over the top secures them in place and adds some protection.
This ring requires about $20 worth of tritium vials, which can be bought from [the-mad-nuclear-scientists](http://www.ebay.com.au/itm/Tritium-Lamp-Vial-Tube-Capsule-Trigalight-6mm-x-1-5-mm-Glow-in-the-Dark-/131195842787?pt=UK_Collectables_Scientific_MJ&var&hash=item1e8be1b0e3&_uhb=1) on ebay. The dimensions of the vial should be 6mm x 1.5 mm.
The inner diameter of this ring is 17mm - you can find ring sizing charts to calculate what that's equivalent to. Scaling up will probably work okay - try to preserve the z height though. If you need to make the ring smaller, you'll need to fiddle around with the file in blender.
