Two STL sizes turn a used Yankee Candle Mini jar into a fruit-fly trap
A July 27 Printables update gives solo sellers two fit-specific STL lids for a compact, commercially usable summer household accessory, with clear attribution and fit-testing notes.
The pick
Fruit Fly Trap fits Yankee Candle Mini Jars by drachenfire7784 is a small household accessory: print a lid, add bait, and reuse a Yankee Candle Mini jar as a fruit-fly and small-insect trap. The model page says it was updated July 27, 2026, and the two STL files on the official file list carry that same date. The creator's original upload time is not separately exposed, so treat July 27 as a verified freshness signal, not as a precise creation timestamp. 1
This is not a popularity pick: the page shows zero reviews and six collections. It is a useful product pick because the fit problem is explicit, the object is compact, and the buyer can reuse a jar that is otherwise headed for the recycling bin. 1
Why it could sell
The best customer is not someone shopping for a novelty print. It is a household with summer fruit flies, a used mini candle jar, and no interest in buying a bulky trap. The creator's description specifically connects the design to a summer fruit-fly problem and suggests apple cider vinegar with a drop or two of dish soap as bait. 1
Sell the lid as a jar-reuse accessory, not as an official Yankee Candle product. The cleanest first listing is one lid in a bright kitchen color, with the required jar diameter called out in the first image and title. A sensible test price is $7-$12 for one lid or $12-$18 for a two-size pair. Those are starting prices, not observed market averages; adjust for packaging, postage, and the time you spend answering fit questions.
A second route is a small seasonal bundle: one lid, a printed fit card, and a note telling the buyer which jar diameter to measure. Let the customer supply the jar. That keeps shipping light and avoids implying that the brand named in the compatibility description sponsors the product.
Files and fit versions
FruitFly-Candle-Lid_51mm.stl— for the original Yankee Candle Mini jar with a tapered neck.FruitFly-Candle-Lid_53mm.stl— for the current Mini jar without a neck.
Both files are listed at 244 kB and 23 mm high. If your printer or filament changes the fit, the creator recommends adjusting X and Y only and leaving Z at 23 mm. Print one sample against the exact jar style you plan to sell before making a batch. 2
Print setup
The creator does not publish a slicer profile, so the settings below are a conservative starting point rather than source-stated values.
| Setting | Starting point | Why it fits this pick |
|---|---|---|
| Layer height | 0.20 mm | Fast enough for a small lid; use 0.16 mm if the rim or cone needs a cleaner finish. |
| Infill | 15-20% | The lid is mostly a shell. Increase it only if your slicer preview leaves a weak top surface. |
| Supports | Off to start | Check the preview around the funnel and rim; add light tree supports only where your printer shows a failing overhang. |
| Material | PLA | Easy, low-cost, and suitable for a dry indoor accessory. Use PETG if the product will sit in a hot, sunny window. |
| Bed adhesion | Clean plate; small brim if needed | The footprint is circular. A brim is a fix for edge lift, not a default requirement. |
Time and difficulty
Plan on roughly 30-60 minutes per lid on a 0.4 mm nozzle at 0.20 mm layers. That is a planning estimate, not a time published by the creator; let your slicer provide the number for each fit version and printer.
Difficulty is easy. The print is a single small part, but the important quality check happens after the printer stops: remove any brim, seat the lid on the correct jar, and confirm that the rim is snug without forcing the glass. If the lid rocks or falls through, switch between the 51 mm and 53 mm files before changing the model's Z height.
Filament and color ideas
- Red or orange PLA: matches the maker's photographed version and reads clearly in a product photo.
- White or warm gray PLA: a quieter kitchen look for buyers who do not want a bright object on the counter.
- Black PLA: hides bait stains, but makes the funnel and rim harder to see in listing photos.
- PETG: a useful second SKU for sunny kitchens, provided the fit is retested; do not assume that changing material preserves the same diameter.
License and listing notes
The official file list includes a
FruitFly-Candle-Lid-License.txt file labeled CC-BY-SA 4.0. The Creative Commons deed allows sharing and adaptation for commercial purposes, including commercially, as long as the license terms are followed. Attribution requires appropriate credit, a link to the license, and an indication of changes. If you modify the design, ShareAlike requires the adapted contribution to use the same license. 2 3A practical listing credit would name drachenfire7784, link the Printables model, link the CC BY-SA 4.0 deed, and say whether you changed the file. Do not use Yankee Candle logos, imply endorsement, or promise a pest-control result that the model page does not establish.
Verdict
A good low-cost summer prototype with a real commercial-use path. The two fit-specific STLs solve the main source of returns, the object is small enough for batch testing, and the license is more useful to a seller than a personal-use-only file. Start with the lid-only SKU, print one 51 mm and one 53 mm sample, and photograph both on plain unbranded jars. If the fit is reliable, test a two-color pair before investing in a larger seasonal run.
