Generating, editing and previewing a part is unlimited on every plan, including the free one. The meter only moves when a file leaves your browser, so you can iterate until it is right and only spend a credit on the version you actually print.
Prices in US dollars, excluding any tax your country adds at checkout. Payments are handled by Paddle, which is the merchant of record and shows you the total in your own currency before you pay.
Need one gear, not a plan? Buy downloads outright. Pack credits never expire, work on any account, and your monthly allowance is always spent first.
Exporting an STL, a 3MF or a STEP file spends one credit. A multi-part model downloaded as separate files spends one credit for the whole set, not one per part, because it is one design leaving the browser.
Browsing the catalogue, changing parameters, chatting to the editor, running clearance checks and rotating the model in the viewport cost nothing and are not counted. Regenerate as many times as you like.
