Discription

This 3D printed light bulb is inspired by a standard E27 bulb. It has a dim glow, with seemingly no connection to the power grid. The dome of the bulb is printed in a translucent PLA, while the screw base is in a gray non-translucent PLA.

From a coin cell battery and an LED you will get a dim lighting for a short period of time.

The dome might take a couple tries to get right, and the top screw part might not look perfect, but if it screws into the base you are fine.

Assembly

For the assembly you will need one CR2032 coin cell battery, and one white/blue/green 5 mm LED. Do not use a red/amber as it can generate heat.

Drop a CR2032 coin cell battery into the slot in the screw base. Then place the 5mm light emitting diode with the anode (the longest leg) on the positive side of the battery. When the LED lights up, you can go ahead and screw the dome in place.

For a longer duration of the light, it is also possible to connect a resistor between the anode and the positive source, but the ligth will be a little darker.

Be sure to recycle your depleted betteries!
