1 inch outer diameter Led module.

So this is a cheap and simple led and lens holding module and base. Made this in about 20 min, so if it doesn't fit that's probably why but everything should work fine.

To clarify, it is sized to hold an led on a star board and a lens for prop lightsaber building.

Unless you are printing in a metal filament, be wary of the heat transfer, as led's do get warm.

I am planning to cast the base in a tin/zinc/copper alloy(melting pennies). If you use thermal glue and glue a penny or two between the led and base it MIGHT work for heat dissipation, but don't come crying to me if you melt the thing.
