This tiny, lightweight keyring has three tritium vials embedded in it. I've uploaded two variants: one using 10x2.5mm vials (see pics) and one using 12x3mm but drop me a message if you'd like to try it with a different size.
The print must be paused at a specific layer so the vials can be pushed into the print before being resumed. After it has finished the vials can only be removed by carefully cutting into the keyring. I recommend the green vials as they are the brightest.
**Safety notes**
----------
Please read up about tritium before working with it. It is radioactive and potentially harmful if a vial breaks. Vials are quite delicate and can break open under pressure or theoretically if they come in direct contact with your printer's hot end.
It's worth printing a trial run first and dialing out any stringing as this could block the vials from being inserted fully. Vials must be completely flush with the top of the part before the print is resumed!
