Introduction: Christmas Box Ornament
For our 3D printing class, we were assigned a group project: write an Instructable about something 3D-printing related. Our group- Janelle, Sam, Chris, Justin, and Jessica- decided to write an Instructable over how we 3D printed a Christmas ornament. So, here's how we did it.
Step 1: Open Tinkercad
Tinkercad is a free, 3D CAD design tool. You can access the site at: www.tinkercad.com. Either sign in or sign up to access your dashboard. From there, click on "Create new design."
Step 2: Place a Ruler
Now that you have started your design, place a ruler down for better measurements.
Step 3: Creating the Box
Create and resize your box.
- Example dimensions: 50mm×50mm×50mm.
Step 4: Creating the Hole for the Box
Create a box-sized hole just a little smaller than the original box. Also, raise the box up off the ground 2 or 3 millimeters.
- Example dimensions: 47mmx47mmx47mm
Step 5: Putting the Box Together
Center and top align the two boxes and group them together.
Step 6: Creating the Lid
Set the grouped shape aside, and then create and resize an additional box.
- Example dimensions: 55mm×55mm×25mm
Step 7: Creating the Hole for the Lid
Basically resize step 4 (the box-sized hole) with different dimensions.
- Example dimensions: 51mmx51mmx22mm
Step 8: Putting the Lid Together
Align the the hole and the lid just like before and group them together.
Step 9: Flipping the Lid
Rotate your lid 180 degrees.
Step 10: Creating the Ring
In order to hang our ornament from our Christmas tree, we will need a place to attach our string. Create a torus shape.
- Example dimensions: 20mm×20mm×5mm
Step 11: Cutting the Ring in Half
Rotate the ring 90 degrees. Cove half of the ring with a box-shaped hole and group the object together to cut the shape in half.
Step 12: Printing the Finished Product
Place your half-ring next to the box and the lid. For the sake of easy/quick printing, we will glue the ring on after the ornament is printed. Now it is time to print!
Step 13: Printing (Cont'd)
First, export your file as an .stl. For our project, we uploaded the ornament and printed it from the printing program Print Studio, which is connected to our 3D40 Dremel Idea Builder. The material we used to print was Octave PLA filament in the color red.
Step 14: Putting the Ring On
Glue the ring to a corner of the lid.
Step 15: Preparing to Tie the Bow
For our ornament, we picked up simple white ribbon from Walmart. We measured out two pieces of ribbon long enough to wrap around the box, placed them in a cross shape across the top of the lid, and then glued the ribbons down
Step 16: Tying the Bow
For our Christmas ornament, we tied a bunny ear bow and then glued it to the top of the lid
To tie a bunny ear bow:
At the center of the ribbon form 2 evenly sized loops in each hand. This should create the bunny ear shape.
Take the right loop and cross it over the left one.
Fold the right loop behind the left and thread it back through the center.
Feed the right loop through the center and pull both loops away from each other creating a tight knot.
Adjust the length of each loop. You can also cut the ends of the ribbon in a diagonal or V shape for a more finished look.
Here's a great video we found that also shows how to tie a bunny ear bow: Bunny Ear Bow
Step 17: Adding the Ribbon to Hang the Ornament
We used left over white ribbon, looped it through the ring, and tied the ends together. Now we can hang our ornament from our tree.
