Summary

Lamp enclosure to fit battery-powered leds, with a clear-printed light diffuser.
You can fit 1 battery in the small one and 2 in the long one.
The body and cap are printed without supports to be able to use the screw.

The diffuser is meant to be printed in clear plastic in order to diffuse light.

Personally, I used it with 4x3W LEDs on a thermal diffuser to cool them, and a 21700 battery.

There is a cap using a 6x5mm JST connector to charge, and one with USB C.
For the USB C cap you can fit only a small charging module, 15mm width maximum.

You can make your own cap, the screw is M33x3.5 ISO.
