A two-colour pumpkin box for a jar candle, uploaded September 18

Fall shoppers buy a finished object, and this week's pick arrives with the finishing touch designed into it: a printed pumpkin that holds a jar candle. Morass published the Pumpkin Box on Cults3D on September 18, 2026, free to download and under a CC BY license. 1 CC BY is the license that lets a seller print physical copies and sell them, which puts this one in a different class from the personal-use listings that dominate the free tier on Cults3D. 2

The shape is a working pumpkin rather than a novelty: ten uneven lobes, deep creases running up into the crown, and a bent, ridged stem. The lid lifts off at the shoulder, and the cavity underneath was drawn around a Ø80 × 70 mm jar candle. That measurement is what turns a decorative print into a gift set, because the candle goes in before the lid does.

The listing states the size of every part, which is unusual for a free model and useful when you are working out how many fit on a plate. 1

The two lid files are alternatives, not a pair. pumpkin_lid_1c.stl fuses the lid and stem into one solid for a single-colour printer. pumpkin_lid_2c.stl keeps them as two named solids in one file, so a multi-colour printer or an AMS unit can run orange for the lid and green for the stem in a single job. The seated box measures a 131 × 127 mm footprint and stands 117 mm tall with the stem on. 1

Under the lid, the cavity seats at Ø82 × 71.5 mm and the designer drew the payload volume at Ø80 × 70 mm around a jar candle. Sweets, tea lights, a bag of treats and a small plant pot were all listed as fitting the same space.

One fit detail decides whether the finished box reads as a real pumpkin or as a misaligned print. The ten lobes all differ in width and depth, so the lid lines up with the body in exactly one rotation. The seating groove is round, so the lid will drop on at any angle and sit level; the creases only run straight across the joint at that one position. Turn the lid slowly until the lobes and the deep creases continue through the seam, then mark that spot with a pen dot inside the rim. The rim carries a 2.4 × 5 mm lip and the lid a matching groove with 0.25 mm of clearance per side, so the lid self-centres and cannot slide sideways once it is on.

Open the official Cults3D listing and take the free download there. The model is free because it is entered in Cults3D's Halloween 2026 modeling contest, and the designer notes that the file stays exclusive to Cults3D until that contest closes on November 15, 2026. 3 The contest window covers where the file is hosted. It leaves printing and selling physical copies untouched.

Cults3D delivers the file through its own download flow, so the listing page is the acquisition route and there is no anonymous direct file address to hand over here. The download is a single ZIP holding all five STLs, which is what you want when the parts have to match each other across plates.

The creator published settings alongside the model. The table starts with those and fills the gaps with editorial starting points, marked as such.

The lid's underside groove bridges 2.9 mm, which a 0.20 mm layer height handles without support. If bridging sags on your machine, raise cooling before you change anything else.

Estimated print time: about 10 to 15 hours in total across the body, lid and stem at 0.20 mm with the settings above on a modern FDM printer. The body carries most of that. These are editorial estimates, not creator figures — the listing does not publish print times.

Difficulty: intermediate. The printing itself is straightforward because nothing needs support and every part sits flat. The work is in the fit: split the lid correctly if you want two colours, and confirm the lobe alignment before you batch.

Filament: an estimated 120 to 180 g of PLA for a full set, which puts raw material at roughly $3 to $5 at current PLA prices. PETG costs slightly more per kilogram and the same weight.

The candle gift set is the product. A printed pumpkin with a scented jar candle inside sells as a finished gift for an estimated $24 to $34 at craft fairs and on a DTC storefront, and the seller's landed cost stays near $6 to $11 once the candle is included. The box is also a treat container for October and a table centrepiece for Thanksgiving.

That second reading is the reason this pick holds up past October 31. A carved jack-o'-lantern has a one-week selling life. A plain pumpkin that opens reads as harvest decor from late September through the end of November, which gives a solo seller roughly nine weeks of demand from one set of files. 1

Three buyer groups are worth targeting:

Package the gift-set version with the candle in the box, the lid seated in its one alignment, and a small card explaining that the lid lifts off at the shoulder and turns back on. That card solves the buyer's first problem, which is working out how the thing opens.

The listing carries a CC BY license, and Cults3D defines that license as Attribution 4.0 International. Its own summary of the terms authorizes you to "Share — copy, distribute and communicate the material by any means and in any format" and to "Adapt — remix, transform and create from the material for any use, including commercial", with one restriction: "No sharing, no adaptation without attribution." 24 Selling printed pumpkins is squarely inside those terms. 5

Attribution is the obligation you have to meet, so credit Morass by name and link the model listing in your product page, your packaging insert or both. The Cults3D license page also notes that Creative Commons licenses are irrevocable for as long as the copyright lasts, which is why a license this clear is worth prioritising over a free file with vague terms. 2

Two practical notes. The file is a free contest entry until November 15, 2026, and contest entries on Cults3D can be edited by their designers during the window, so download once and keep your own copy of the version you validated. And the model is parametric work by a designer who publishes the rest of his catalogue at morass.github.io/prints, which is the place to look if you want to know whether more sizes are coming. 6

Prototype this one if you sell fall decor or gift sets. The commercial license needs no membership, no per-sale fee and no separate permission, the designer published dimensions and settings precise enough to slice without guesswork, and the candle cavity gives you a finished product rather than a decorative blank.

Print one set, seat the lid until the creases line up, and put a Ø80 × 70 mm jar candle inside it before you decide anything else. Demand is the unproven part: the listing showed 381 views, 0 likes and 6 downloads when this was written, which is normal for a model uploaded the day before and tells you nothing either way. 1 Your own first sample, timed on your machine with your candle supplier's jar in hand, is the number that decides whether the gift set belongs in your catalogue for the next nine weeks.
