About: I love coming up with new projects to challenge myself and to express my creativity. Make It is about me sharing that passion with you!

Intro: How to Make a 3D Printed Ornament

Create your own 3D printed LED ornament!

Print the parts and add a simple circuit to spice up your tree!

Step 1: Video

Watch this video instead of the written tutorial, or use it to see the steps performed while following along!

Step 2: Supplies

Electrical Tape

Coin Cell Battery

White LEDs


The print is made from 3 Parts. The star top, the container and the hook

Soldering Tools
Hot Glue Gun

Step 3: Wires

Cut and strip 3, 2" long wires. On 2 of the wires, strip one side longer than the rest. The longer bit will connect to the battery.

Step 4: Soldering

First solder one of the wires to a pin on the switch. Then solder another wire to a pin adjacent to the last pin you soldered to.

Depending on your LED, you may have to trim the pins a bit.

Solder a wire from the switch to a pin on the LED and then solder the 3rd wire to the other pin.

Refer to the diagram if you have trouble, but the circuit is very simple.

Step 5: Assembly

First we're going to attach the switch. I placed a small dab of hot glue at the base of the switch hole and pushed the switch into place. Then I secured the rest with more hot glue. Make sure you don't force glue into the cavity in which the switch moves. Check if it can still work.

Next I pushed the small 3D printed hook through the slot in the side of the container and then glued it in place.

Step 6: Attaching the Battery

I didn't want to solder wires to the battery, so instead I decided to use electrical tape. Spread the copper wire across each side and wrap tape around the coin cell. I chose to do this with the switch in the ON position in order to get the right polarity of the battery. You can add a dab of hot glue at the base of the battery to hold the wires in place.

Step 7: Assembly Pt. 2

With the electronics finished, I placed the battery in the bottom of the container. Then I pushed the LED into the whole in the back of the star. The final step was to snap the top onto the container!

Step 8: Hang the Ornament!

Hang the ornament on your tree and put it on display!
