30 Creative 3D Pen Project Ideas for Kids — Beginner to Advanced
Once your child has the basics down, the real fun begins — 3D pens can make everything from flat name tags and butterflies to multi-part 3D dinosaurs, jewellery, and architectural builds. Below: 30 project ideas organised by difficulty, with time estimates, recommended colours, and which pen works best for each.
We've grouped projects into three skill levels:
- Beginner (1-10): Flat shapes peeled off paper, simple traces. Most kids can attempt these in their first session
- Intermediate (11-20): Multi-part builds, layered 3D shapes, tracing more complex stencils. Suits ages 7+ with a few sessions of practice
- Advanced (21-30): Mid-air drawing, complex assemblies, jewellery and decor pieces. Best for ages 9+ or experienced kids of any age
All projects work with both PCL (low-temp) and PLA (high-temp) pens unless specified.
Beginner projects (ages 5+)
These are flat-shape drawings on paper. Once finished, peel the cooled filament off and admire — or join multiple flat pieces together for a simple 3D effect.
1. Heart name tag
Trace a heart outline on paper, fill in the centre with one colour, then write your child's name across the middle in a contrasting colour. Peel off — instant fridge magnet (with a sticky-back magnet) or backpack tag.
- Difficulty: ⭐
- Time: 5 minutes
- Colours used: 2-3
- Best with: Any pen
2. Simple star
Draw a 5-pointed star outline, fill in. Great Christmas tree decoration when threaded with cord.
- Difficulty: ⭐
- Time: 3 minutes
- Colours used: 1-2
3. Flower with petals
Draw a centre dot, then 5-6 oval petals around it. Peel and arrange. Stack 2-3 layers of petals (smaller on top) for a 3D effect.
- Difficulty: ⭐
- Time: 5 minutes
- Colours used: 2 (centre + petals)
4. Simple butterfly
Trace a butterfly stencil (in our Premium 30c kit) or freehand symmetrical wings + body. Outline first, fill with patterns. Big visual impact for low effort.
- Difficulty: ⭐

6. Crown / tiara
Draw a wavy crown shape with points, fill in, add small jewel-coloured dots along the band. Wear on the head with the warm filament still slightly bendable.
- Difficulty: ⭐⭐

- Colours used: 2-3
7. Letter of the alphabet
Trace a single big letter (your child's initial works well) — outline, then fill. Stack 2-3 letters to spell a name.
- Difficulty: ⭐
- Time: 5 minutes per letter

Intermediate projects (ages 7-9)
Now we move from flat-only to layered or joined 3D shapes. The technique is: draw flat pieces, peel them off, then bond them together at the edges by touching the pen tip to the join and adding a thin line of filament.
11. 3D house
Draw 4 walls (rectangles), a triangular roof, a door, and 2 windows as flat pieces. Peel off, then join the wall edges at right angles using the pen tip to bond. Stick the roof on top. Your first 3D model!
- Difficulty: ⭐⭐
- Time: 25 minutes
- Colours used: 3-5
12. Glasses / sunglasses
Draw two oval frames connected by a small bridge, then 2 long arms that fold out. Peel off and try them on.
- Difficulty: ⭐⭐
- Time: 15 minutes
- Colours used: 1-2
13. Bracelet
Draw a strip the length of your wrist, with a decorative pattern (waves, dots, flowers, diamonds). Peel off, bend around your wrist while still slightly warm, bond the ends together.
- Difficulty: ⭐⭐
- Time: 12 minutes
- Colours used: 2-4
14. Photo frame
Draw a rectangle border with intricate decoration — flowers, vines, geometric patterns. Make 2 the same size, glue (or pen-bond) them together with a photo sandwiched between.
- Difficulty: ⭐⭐⭐
- Time: 30 minutes
- Colours used: 3-5
15. Animal (dog, cat, fish)
Trace an animal stencil or freehand. Outline, fill, add details (eyes, nose, fur lines, scales). Peel and stand up by attaching small "feet" stubs to the underside.
- Difficulty: ⭐⭐⭐
- Time: 25 minutes

17. Mini Christmas ornament
Draw a circle, fill in with a Christmas pattern (candy cane, snowflake, gingerbread man, tree). Add a loop at the top for hanging.
- Difficulty: ⭐⭐
- Time: 15 minutes

21. 3D bicycle
Draw 2 wheels (circles with spokes), a frame (triangular shape), handlebars, seat. Peel off and assemble — the wheels mount on the frame, the handlebars and seat attach. Time-consuming but impressive.
- Difficulty: ⭐⭐⭐⭐
- Time: 45 minutes
- Colours used: 3-4
- Best with: 40c kit + stencils
22. Dinosaur model

- Colours used: 1-2 (typically all one colour for architectural look)
27. Solar system mobile
Draw 9 spheres (sun, planets) — each at a different size. Suspend with thin strings from a wooden rod. Glow-in-the-dark filament makes this magical at night (search for special filament).
- Difficulty: ⭐⭐⭐⭐
- Time: 60 minutes

28. Custom phone stand
Draw a base + a back support angled at ~70°. Use thicker filament lines for stability. Personalise with your child's name. Functional gift.

Tips for project success
Start flat. All 3D builds begin as flat pieces. Don't try mid-air 3D drawing in the first 5 sessions — it takes practice that beginners haven't built yet.
Use stencils. They aren't cheating — professional 3D pen artists use stencils too. Stencils handle the "what should I draw?" question so kids can focus on technique. Our Premium 30c kit includes a stencil set, or download free PDFs from Pinterest.
Plan colours before you start. Pulling out the strands you'll need in advance saves time and avoids getting stuck mid-project hunting for that one specific shade.
Bond with the pen tip. When joining flat pieces, gently touch the pen tip to the join and add a thin line of filament. The fresh hot filament melts a tiny bit of the existing piece and creates a strong bond once cooled.
Stack flat pieces for 3D depth. A "3D" flower can be 3 stacked petal layers (smaller on top) — much easier than mid-air drawing a real 3D flower. Looks impressive, beginner-friendly.
Save scrap filament. Short bits left over from projects make great small details — eyes, dots, decoration, mini flowers. Keep them in a clear jar so they're easy to find.
Take photos. Kids forget what they made. Snap a quick photo of every finished piece — by the end of a school holiday they'll have 20+ projects to show off.

Frequently asked questions
What's the easiest 3D pen project to start with?
A flat heart or star on paper. 5 minutes, 1-2 colours, clean peel-off. Builds confidence that the pen works and the technique is achievable.
How long do 3D pen creations last?
PCL pieces stay flexible and last for years if not bent or stretched. PLA pieces are rigid and last indefinitely indoors (UV exposure outdoors will eventually cause cracking — keep them inside).
Can I sell my child's 3D pen creations?
Yes — kids' 3D pen creations sell well at school markets, craft fairs, and via online platforms like Etsy or Trade Me. Common items: name tags, jewellery, fridge magnets, Christmas ornaments, cake toppers. Pricing $5-$20 per item is typical for handmade kid-made craft.
What's the best 3D pen project for school holidays?
A multi-day project like a dollhouse, dinosaur, or solar system mobile (advanced). Spreads across 3-5 sessions, gives kids a real sense of accomplishment, and produces something genuinely impressive.
Can I 3D-pen on top of a 3D printed object?
Yes — adding hand-drawn detail to 3D-printed parts is a common use of 3D pens for adult hobbyists. Kids can decorate plain 3D-printed phone cases, miniature figures, or models with their own designs.
What if my child gets stuck or frustrated?
Switch to a stencil for the next session. The "what to draw" mental block is the #1 reason kids stop using 3D pens. Stencils give them a clear, achievable target. Once they finish 2-3 stencils, the confidence usually returns and they start inventing again.
How long does each project take?
Beginner: 3-15 minutes. Intermediate: 15-35 minutes. Advanced: 30-90 minutes. Most kids do 1-2 projects per session.
Can I display finished 3D pen pieces?
Absolutely. Great places: a shelf in their room, a corkboard in the kitchen, a string of "best of" pieces hung from a shelf, or a glass-fronted display box. They're more durable than they look — survive years of normal handling.
What's next?
