Three steps, then you go back to designing

01 — 03
01

Upload the file

STL, STEP or 3MF for printing. DXF or SVG for laser-cut parts once cutting opens, with the material and thickness you designed it for.

02

Set what you earn

We calculate what the part costs to make. You slide the retail price to whatever you think the idea is worth — the difference is yours, on every unit.

03

We make it and ship it

Printed to order, packed and posted from Poland to anywhere in the EU. You get paid monthly. You never see an order.

The boring half is ours

Most good designs never get published because selling them is a second job. On concept.forsale you licence the design to us and we act as the manufacturer and the seller.

That means you do not need a company, a VAT number, a courier account or a returns policy to earn from what you designed.

Production
Our printers, our filament, our quality check on every part.
Packing and shipping
Tracked parcels across the EU, labels printed at the machine.
VAT and invoicing
Country-correct VAT settled by us. You get a royalty statement.
Product responsibility
We are the responsible economic operator under EU rules.
Returns and support
Buyers write to us, not to you. Reprints are on the house.
Your file stays yours
We sell printed parts, never the file. Pull the listing whenever you want.
