Mini Cauldron

Regardless of the time of year, this mini cauldron is a versatile and cute conversation piece. It's perfect for holding loose change, jewelry, and other small items. It can even be used as a planter for succulents!

I am currently a sophomore at North Broward Preparatory High School.

• Fusion 360
• 3D printer
• Filament
• Some sharp tools to remove supports

1. Create >> Cylinder.
2. Make the cylinder starting from the center of the work plane.
3. Make the cylinder's diameter 50 mm & its height 8 mm.
4. Create >> Sphere.
5. Make the sphere in the middle of the cylinder so part of it is attached to the cylinder.
6. Make the sphere's dimensions 70 mm.
7. Modify >> Combine.
8. Select the sphere as the target body and the cylinder as the tool body.
9. Operation >> cut.

Torus A

1. Create >> torus.
2. Make the torus centered with the sphere but slightly raised off the work plane.
3. Make the inner diameter of the torus 35 mm and the outer diameter 70 mm.
4. Modify >> Combine.
5. Target body: sphere and tool body: torus.
6. Operation >> Cut.

Torus B

1. Create >> torus.
2. Make the torus centered with the sphere body and raised so it is centered with the opening from torus A (refer to picture).
3. Make the inner diameter of the torus 20 mm and the outer diameter 65 mm.
4. Modify >> Move/Copy.
5. Translate the torus B so it is centered with torus A (refer to pictures).
6. Modify >> Cut torus B into torus A.

There is an opening in the cauldron in the photos above. Just ignore this because it will be part of the next step.

1. Modify >> Shell.
2. Select the cauldron body & check the box labeled "Tangent Chain".
3. Inside thickness: 3 mm and direction: inside.
4. Create >> Cylinder.
5. Starting from the center of the cauldron, create a cylinder that has 65 mm diameter and 30 mm height.
6. Modify >> Move/Copy.
7. Translate the cylinder so it is centered with the cauldron body and right above the opening. The cylinder should touch the cauldron enough so it creates an opening but not too much that it cuts deeply into the cauldron body.
8. Modify >> Combine.
9. Cut the cylinder into the cauldron body.
10. Create >> Torus.
11. Starting from the center of the cauldron, create a torus with a 57 mm inner diameter and a 6.5 mm torus diameter (do not confuse "torus diameter" with "outer diameter").
12. Modify >> Move/Copy.
13. Translate the torus so it is right on top of the opening (refer to pictures).

1. Create >> Create Sketch.
2. Select the YZ plane (refer to picture).
3. Click on "line" to create a line about 4 units (boxes) long.
4. Click on the checkmark.
5. Click on "spline" to create an arc over the line by clicking on the points shown in the picture. The sketch should now be in the shape of a bow.
6. Click on the checkmark.
7. Click "Finish Sketch".
8. Create >> Revolve.
9. Select on the sketch as the profile and the line as the axis.
10. Type: Angle and Angle: 360º.
11. Direction: One Side and Operation: New Body.
12. Create >> Box.
13. Make the box any size as long as it is big enough to cut into half of the handle base.
14. Modify >> Combine.
15. Cut the box into handle base so half of the base is gone.
16. Modify >> Move/Copy
17. Make sure your "Move Object" is "Bodies" at all times!
18. Rotate the handle base 90º.
19. Modify >> Move/Copy.
20. Select the handle base.
21. Move object: Bodies, move type: translate
22. Check the box labeled "Create Copy".
23. Translate the handle base to the right (refer to picture). This should create two copies of the handle base; one on the left and one on the right.
24. Modify >> Move/Copy.
25. Move the handle bases so they are attached to each side (left & right) of the cauldron. Each handle base should be slightly above the middle of each side (refer to pictures).

1. Create >> Torus.
2. Create the torus on the YZ plane.
3. Make the inner diameter of the torus 8 mm and the torus diameter 3 mm.
4. Modify >> Move/Copy.
5. Move object: Bodies, move type: translate
6. Check the box labeled "Create Copy".
7. Translate the torus to the right (refer to picture). This should create two copies; one on the left & one on the right.
8. Modify >> Move/Copy
9. Move the tori so they are attached to each of the handle base. The top of each torus should be in the middle of each handle base (refer to pictures).
10. Modify >> Combine.
11. Select the entire cauldron and click "join".
12. Save your design and upload it as an STL.

Note: In my design, my handles are on the small side so you can manipulate the size of the tori to get your desired look.

I used PrusaSlicer to print this design.

1. Add supports underneath the cauldron handles.
2. Print and enjoy your cute mini cauldron!
