1 Vial Tritium Ring

This ring has a slot to hold a single 1.5mm x 6mm vial of tritium.

It is nice to fiddle with or play with in the dark. Could be useful on a keychain.

When you print it, I recommend inserting the vial while the model is still warm, so that when the ring cools and shrinks, it can fit snuggly around the vial.

Use rafts and supports (touching buildplate only) and print it a couple millimetres in the air.

Dimensions:
Height: 8mm
Outer diameter: 23mm
Inner diameter: 18mm
