Today's pick is a functional one: armature vitrine pour plaques acrylique, a printable display case frame uploaded to Cults3D on May 22, 2026 by designer picolorigolo (CC BY-SA, commercial use confirmed).1 If you already sell printed figurines or collectibles on Etsy, this frame is a direct upsell. If you want a standalone listing that's short to print and easy to explain, it's that too.

What it is

The armature vitrine is a three-part frame designed to hold two 10×15×1 mm acrylic sheets — a standard size sold on Amazon and most craft supply sites.1 The designer notes that two of those sheets need to be trimmed down to 10×10 mm for assembly.1
The three STL files break down like this:
  • montant (vertical post) — 5.5 × 5.5 × 105.7 mm, the corner uprights
  • socle (base plate) — 165 × 115 × 5.2 mm
  • sommet (top plate) — 165 × 115 × 5.6 mm
picolorigolo is the same designer behind a long-running numbered series of Napoleonic soldier miniatures — 156 models, 9.7k total downloads, with Designer, Popular, and Influencer badges on Cults3D.1 The vitrine was designed to display those same figurines — the reference photo on the model page shows a pair of painted Napoleonic soldiers standing inside the assembled frame.

License

CC BY-SA — commercial use is explicitly permitted, including selling printed units.1 Two obligations apply:
  • Attribution: credit picolorigolo as the designer. A line in your Etsy listing description ("Printed from a design by picolorigolo / Cults3D") is sufficient.
  • Share-alike: applies only to derivative digital files you publish — if you remix the STL and release it publicly, that file must also be CC BY-SA. Selling a physical print is not a derivative work; you are not required to publish anything.
No Patreon subscription. No per-unit fee. The license is perpetual.

Print settings

Three separate prints, no assembly complexity beyond sliding the acrylic sheets in. The posts (montant) are the only parts that require any attention — they're thin and tall relative to their footprint, so a brim is worth it.
ParameterRecommended value
Layer height0.15–0.20 mm
Infill15–20%
SupportsNot required for socle or sommet; montant may need a brim or raft
Bed adhesionBrim on montant
MaterialPLA or PLA+
Print time estimate~3–5 hours total for one full set
DifficultyBeginner to intermediate
Post-processingLight sanding or cleanup on montant base if brim is used
The socle and sommet are flat plates — they print fast and clean. Run all four montants in one print job to save time.

Filament suggestion

Matte black or dark charcoal PLA is the natural choice here. The frame disappears visually and lets the contents (figurines, small collectibles, jewelry) carry the eye. A neutral color also photographs better for Etsy listings — you're selling what's inside, not the frame itself.
Avoid silk or satin finishes: the sheen reads as cheap on a display product. Matte PLA or matte PLA+ from any mainstream brand works fine. If you plan to offer color variants, a warm white or raw grey also reads well against painted miniatures.

Who buys this and what they'll pay

The clearest buyer is already in your customer list: anyone who purchased a printed figurine from you and wants a way to display it. A display case frame converts a shelf piece into a proper showcase, and it naturally bundles with the figurines you already print.
Beyond the bundle angle, three buyer types will search for this standalone:
  • Miniature painters and collectors who want a clean, open-sided case for 28–90 mm figures without spending $25+ on commercial acrylic boxes
  • Gift buyers pairing a printed figure with its own dedicated display — this is the difference between a "thing I printed" and a "complete gift"
  • Small collectible sellers who make jewelry, resin pieces, or hand-painted miniatures and need an inexpensive display option they can brand or customize
On Etsy, 3D-printed single figurines at 60–90 mm typically list unpainted at $12–$22 and painted at $38–$80 depending on detail and seller reputation.2 Dedicated 3D-printed display case listings in this style were not found during research, so treat the following as reasoned pricing guidance rather than observed Etsy comps: an add-on bundle price of $8–$15 (case only) or a standalone listing at $18–$28 (case + acrylic sheets included) would sit below the cost of commercial acrylic display boxes while maintaining healthy margin. The acrylic sheets are the only physical BOM item the buyer cannot print themselves — include them in the package to reduce buyer friction.

Cost model

The cost per set depends on whether you source the acrylic sheets at scale. A standard 10×15 mm acrylic sheet pack runs roughly $0.20–$0.40 per sheet in bulk (the designer links to an Amazon listing).1
Cost itemEstimate
PLA filament (~35 g total at $0.02/g)$0.70
Acrylic sheets × 2 (standard retail)$0.50–$0.80
Packaging (small rigid mailer or box)$0.50
Total per-unit material cost~$1.70–$2.00
Etsy fees (~12% of sale + $0.20 listing)~$1.80–$3.56 (at $13–$28 price)
Net at $15 (add-on price)~$10.30 (~69% margin, pre-shipping)
Net at $25 (standalone with acrylic)~$18.00 (~72% margin, pre-shipping)
All material cost figures are author estimates; filament assumes a $20/kg spool. Acrylic sheet cost assumes bulk purchase. Etsy fees use a standard seller account. Shipping not included — this ships flat in a padded envelope under 4 oz.
