I ordered eleven rolls of filament and paid nothing for them. No discount code, no sponsorship, no affiliate deal. The whole order was covered by gift cards I earned from points, and the points came from uploading 3D models I had already designed.
How the loop actually works
Most people know print-sharing platforms exist. Far fewer realise several of them pay you, and almost nobody explains what that payment is actually worth in practice.

One email per experiment. Full numbers, no fluff.
The chain in my case ran like this:
- Upload original models to the platforms that run point systems. I use Cults3D, Thangs, Printables, Makeronline, MakerWorld, Creality Cloud and Nexprint.
- People download and print them, which earns points.
- Points convert into gift cards.
- Gift cards buy real things. In this case, eleven rolls of filament from the Elegoo store, accumulated through Nexprint.
The filament then goes back into printing, which produces more models, which earn more points. That is the part worth paying attention to: it compounds, slowly, without money entering the system at any point.
Why this matters more than it looks
Filament is the running cost of this hobby. It is the reason people conclude that 3D printing cannot pay for itself, because every print quietly spends money before it earns any.
Take the filament cost out and the maths changes completely. A print that earns nothing still costs nothing. You can afford to make things that might not work, which is exactly the freedom you need if you are trying to find out what people actually want to download.
It also sets an obvious question: if points buy filament, what else do they buy? I am currently 33,000 points into a 137,000 point target for a Falcon A1 Pro laser engraver, a machine that sells for around $1,000. Same mechanic, much bigger prize, and I am documenting whether it actually arrives.
The honest caveats
- This is not fast. Eleven rolls represents a long stretch of uploading, not a weekend.
- It rewards volume and consistency, not one good model.
- Points are not cash. You spend them where the platform lets you, and the platform can change the rules.
- It only works if you are designing models anyway. Designing purely to farm points is a job, and not a well paid one.
