This is an additional upgrade to 3D Printy's Lunar Lighthouse Puzzle Box. It uses a 2x12mm vial of tritium gas to make the lamp room self-illuminating.
The lamp room is now mostly filled in, with a small channel to accept a 2x12mm glass vial of tritium.
The optional new cap screws on, and has a centre pin that closes the top of the channel to minimize the movement of the gas vial. You can also use my threaded cap from the upgrade model if the vial of tritium is well secured with glue inside the lamp room.
These parts are not interchangeable with the originals (you can't use the original cap on the new lamp room).
Here is a demonstration of the effect of the tritium vial with glow-in-the-dark filament after 4 hours of darkness (left lamp room has the tritium, right lamp room does not):
T+0
T+4h
Printing and assembly tips
Use a transparent, or glow-in-the-dark, filament with a low infill (10% is recommended).
Print the pieces as oriented in the .stl files.
If there's any stringing in the channel, you can use a bit of 1.75mm filaments to clean it out.
Gently insert the tritium vial into the channel.
Add a drop of superglue at the top of the channel to fully secure it into the print.
Add a few drops of superglue at the lamp room cap threads.
Safety notes
The lamp room, and lamp room cap are choking hazards for children under 3 years old.
Ensure you have the proper knowledge, skills, and training to safely handle radioactive materials. You are responsible for your own actions.
