How 3nxtdoor works
A map of 3D printers in your city. Free to use for both sides.
- 1
Find a maker, or let makers find you
Browse printers on the map and request a print directly, or post a request. Makers nearby see your area light up orange and send offers. For big jobs, makers send sealed quotes you compare side by side.
- 2
Talk here until you agree
Ask questions in the chat on each offer. Phone numbers, UPI IDs and links are removed automatically until an order exists. Each attempt to share them adds a strike; five strikes suspends the account.
- 3
Accept an offer to unlock contact
Accepting creates an order with its own code. The maker's WhatsApp and UPI appear on the order, so you can coordinate and pay directly. 3nxtdoor never holds your money.
- 4
Close it with the handover code
You get a 4-digit code. Give it to the maker only once the print is in your hands. Only orders closed this way count toward a maker's rating, tier and place on the map.
Staying safe when you pay directly
Prefer paying on pickup for local orders. For larger jobs, keep any advance under half the price. Deals made outside an order on 3nxtdoor can't be reviewed, and we can't help if something goes wrong. Report anyone who takes money and doesn't deliver; confirmed scams mean an immediate ban.
Not allowed
Weapons or weapon parts, anything illegal to own, and designs you don't have the right to print, such as branded or licensed characters.
