How to Price 3D Printed Flexi Models
Practical, real-world guidance on pricing flexi prints for FlexiMania flexi print sellers.
Pricing flexi prints is one of the top questions we get from FlexiMania Patreon members. Here's the workflow we recommend, based on years of running our own market tables and shops.
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.
The commercial license question
Before you can sell anything, confirm your STL source allows commercial use. FlexiMania's $10/month Patreon includes a commercial license for physical prints — read the specifics in our commercial license guide.
How to approach pricing flexi prints
A short, practical playbook.
- Pick 5–10 hero models that print in under 3 hours each
- Print at least 3 of each so you always have inventory on hand
- Photograph each model on a plain background with soft daylight
- Set prices at roughly 10× material cost, then adjust after your first market
- Iterate — drop what doesn't sell after 2 events, double down on what does
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

Frequently asked questions
›Do I need a business license?
In most US states, yes, above a small revenue threshold. Check locally — a $50 seller's permit is usually all it takes.
›What's the single highest-margin channel?
In-person craft fairs, by a wide margin. Etsy is a close second.
