GET IT MADE No printer, or the part is too big for yours? Post it as a job on The Spool List, a marketplace that connects buyers with makers who own 3D printers, CNC machines and laser cutters. It's free for buyers, and payments are escrow-protected. If you own a printer, you can earn money printing for others. On MakerWorld, Printables and Thingiverse model pages, a small "No printer? Get this made" card lets you post that model as a job in one click. You can hide it on any site or turn it off in the extension's options. Made by The Spool List: thespoollist.com
