A piggy bank that looks like a boss mob — 3D Print Pick (June 7)
Free STL chibi fire dragon piggy bank by EndK7. Patreon $4/mo unlocks commercial resale. ~67–72% margin at $20 retail.
EndK7 (a German designer with 236 designs and 94.9k downloads across platforms) uploaded this one this morning. 1 It's a fully functional coin bank shaped like a chubby chibi fire dragon — wings, horns, scales, oversized anime eyes, the works. The coin slot is on the back, and coins come out through a threaded screw-cap bolt underneath. It also doubles as a decorative sculpture, which is exactly the kind of product that earns gift-market clicks on Etsy.
The Etsy category for 3D-printed dragon piggy banks is already established. Active listings price from $9.34 to $25.00, with specific comps like a Chubby Dragon Piggy Bank at $19.98 and a Chonky Dragon Coin Bank at $22.80. 1 The model was published today, June 7, 2026 — no community prints yet, which means you can be the first seller in the market with this specific design.
What you're printing
Four separate parts ship in the ZIP download: 1
CuteFireDragon_PiggyBank.stl— the main dragon bodyEyes.stl— separate eye model for printing in a contrasting colorEyes.3mf— pre-painted eyes file for Bambu Studio / OrcaSlicer multi-material systems (AMS/MMU)PiggyBank_Bolt.stl— the threaded screw-cap closure for coin retrieval
The eyes file exists in two formats because EndK7 designed for two workflows: if you have an AMS or MMU, import the
.3mf directly and the color assignments are already mapped. If you're on a single-extruder machine, print Eyes.stl separately in a bright color (yellow works especially well for the fire dragon) and glue them in.The screw-cap bolt is a printed mechanical part. It threads onto the bottom of the body — no hardware, no inserts. Print it in the same filament as the body or in a contrasting accent color if you want to add a detail.
Print settings
The model page specifies supports required. No other settings are listed by the designer. The table below uses standard values for a figure of this type — treat them as a starting point, not designer-confirmed specs.
| Setting | Recommended value |
|---|---|
| Layer height | 0.20 mm |
| Infill | 15–20% |
| Supports | Required (tree supports work well for the wings and horns) |
| Bed adhesion | Brim recommended |
| Material | PLA |
| Print orientation | Upright (seated pose, flat base) |
Estimated print time: approximately 6–10 hours depending on printer speed and support density. The wings, horn clusters, and scale detail on the back create multiple support attachment points — budget time for cleanup.
Difficulty: intermediate. The geometry is straightforward, but the supports around the wings and horn area need careful removal to avoid snapping the thin fin details. Use flush cutters and work slowly on those areas.
Filament
EndK7's demo prints use Polymaker Panchroma Dual Matte PLA — a two-tone filament that shifts between two colors within a single spool. 2 At $22.99/kg, it's more expensive than standard PLA, but it produces a gradient effect (e.g., black body fading to red tips on wings and horns) without requiring an AMS or filament swap. The spool is AMS-compatible with hardened edges if you do want to run it through a multi-material system.
Dual Matte color options that work for a fire dragon theme:
| Colorway | Effect |
|---|---|
| Shadow Red (Black-Red) | Black body, red accents on extremities |
| Shadow Orange (Orange-Black) | Orange base, black fade toward tips |
| Sunrise (Red-Yellow) | Red body transitioning to yellow on horns and wings |
If you're keeping costs down, any single-color PLA works fine for the body — the sculpt reads clearly at one color. Just print the eyes in a contrasting filament (white + black swap, or bright yellow) and glue them in for the full visual effect.
.3mf eyes file makes the white sclera + dark iris combination easy to achieve on any AMS/MMU machine. 1Commercial license

Sales angle and margin
Dragon piggy banks sell on Etsy at $9.34–$25.00 for 3D-printed versions. 1 A $19–22 retail price is well-supported by the category. The dual-color Polymaker Panchroma version justifies the higher end of that range.
Margin estimate at $20 retail, standard PLA (~$20/kg):
| Cost item | Estimated range |
|---|---|
| Filament — single-color PLA (~150–200g) | $3.00–$4.00 |
| Polymaker Panchroma upgrade (~150–200g at $22.99/kg) | $3.45–$4.60 |
| Patreon license ($4/month ÷ estimated 10 units/month) | ~$0.40/unit |
| Etsy fees (~6.5% transaction + $0.20 listing) at $20 | ~$1.50 |
| Packaging (padded mailer) | ~$0.75 |
| Total cost — standard PLA | ~$5.65–$6.65 |
| Total cost — Panchroma dual-matte | ~$6.10–$7.25 |
| Net at $20 retail (standard PLA) | ~$13.35–$14.35 (~67–72%) |
| Net at $20 retail (Panchroma) | ~$12.75–$13.90 (~64–70%) |
Cost estimates are author calculations based on standard filament pricing and designer-specified material. Etsy fee estimate uses Etsy's standard transaction fee structure. Patreon license amortization assumes 10 units/month — if you run higher volume, the per-unit cost drops further.
Who buys this:
- Children's gift market — parents, grandparents, and relatives looking for a functional gift that isn't another toy. "Dragon coin bank for kids" is a real Etsy search term.
- Fantasy/collectible buyers — the sculpt is detailed enough to appeal to dragon collectors who aren't specifically looking for a piggy bank. Listing it under both "dragon figurine" and "piggy bank" captures both audiences.
- Bedroom/shelf decoration — the seated chibi pose reads as home decor first, piggy bank second. Buyers browsing "cute desk decor" can stumble onto it.
Search terms to test: dragon piggy bank, 3D printed coin bank dragon, dragon gift for kids, fantasy piggy bank, cute dragon figurine.
