LED X-Mas Ornament

This model consists of two parts:

1. The top part holding the CR2032 battery and the LED
2. The Ornament

The two parts are screwed together, so you can change the ornament. The ornament is printed in vase mode. I printed it with a line width of 0.6mm (with a 0.4mm nozzle), but you might also try a different line width. Orient the ornament so the wider part is at the bottom. I also used a brim.

The top part is printed “normally” (meaning not in vase mode). The assembly of the top part is a bit fiddly. You will need the following things:

• an LED
• resistor fitting you LED (I didn't need one for my white LED)
• blank wire (0,75 mm²)
• CR2032 battery
• switch with 9x4mm (if you print with more walls you can use a file to make the hole bigger)
• soldering iron
• pliers

Assembly

Cut a piece of wire that is approximately double the height of the top part and bend it in half so it fits the path marked with 1. Put the wire from the top through the holes in the bottom. Then bend the top of the wire to the back at push it through the slot. Bend the wire from the other side so it is somewhat fixed. Do the same with the other side. Position the wires to fit in the paths and insert the battery. That should push the wires in their position (use some pliers to pull out the battery after that). Insert the LED from the bottom (2) and position it to be in the center. Solder 2 wires to the switch and insert it in the hole. Connect and solder the wires. Pay attention to get the polarity right.  When done just screw the two parts together (both parts are printed with threads. You can also put a string/wire through the holes marked with (3) to hang the ornament.

Pay attention when inserting the battery the + side should face the switch. There are markings on the top for that (but they only work if your wiring is correct).
