Print-in-Place STL Files for Christmas
Ornaments, gifts and stocking-fillers — the best Christmas print-in-place STL files to print this season.
Nothing beats gifting something you made yourself — and a working articulated creature is the kind of gift a recipient actually keeps on their desk. Print-in-place STLs are ideal Christmas gifts because they scale down cheaply into stocking-fillers and up into centrepiece dragons.
Everything below has been tested on Bambu Lab, Prusa and generic Ender-class printers with a stock 0.4 mm nozzle. If you want the entire FlexiMania library in one place, we publish new print-in-place models every week on FlexiMania Patreon — one flat $10/month unlocks all 60+ STL & 3MF files.
Best Christmas print-in-place picks
Print any of these in red-and-green PLA and you're done.
Cute Dragon in red silk
Chibi dragon in Christmas red — the crowd-pleaser.
Flexi Snail in gradient PLA
A pastel snail is an unexpected, memorable stocking-filler.
Flexi Caterpillar as a tree ornament
Add a small loop and hang it — the segments catch tree lights beautifully.
Filament palette ideas
Classic Christmas palettes work best.
- Silk red + silk green + silk gold — the timeless combo
- Matte white + silk gold — Scandinavian minimal
- Silk copper + silk emerald — modern maximalist
Slicer settings that make these models sing
You can print any of the models below on any half-decent FDM printer, but you'll get noticeably crisper joints — and higher first-time success — if you dial in the settings below rather than trusting your slicer's defaults.
| Setting | Recommended | Notes |
|---|---|---|
| Layer height | 0.20 mm | Drop to 0.16 mm for tiny joints |
| Nozzle | 0.4 mm | 0.6 mm works if you scale the model up 130%+ |
| Walls | 3 | Extra strength on hinges without swelling clearances |
| Infill | 10–15% | Gyroid or grid — anything denser wastes filament |
| Supports | Off | Never needed on properly designed print-in-place models |
| Cooling | 100% | Especially on the small joint bridges |
| Print speed | ≤ 150 mm/s | Faster prints leave gaps in the joint bridges |
Common mistakes to avoid
Nine out of ten failed print-in-place prints trace back to the same short list of mistakes. Skim it before you slice.
- Turning supports on — print-in-place models never need them, always disable them
- Slicing at 0.28 mm layer height on small joints — drop to 0.20 mm for crisp hinges
- Running cooling below 100% — flexi joints need maximum cooling to release cleanly
- Chasing 300 mm/s print speeds — keep it under 150 mm/s until the model comes off perfectly
- Skipping bed cleaning — a quick IPA wipe fixes 90% of first-layer issues
