Keep 1c3d going. Go Pro.
1c3d is built and run by one person. Pro is how members help pay for the servers and the time it takes to keep writing guides and building tools. You get a PRO badge and a set of extras as a thank-you.
Payments are handled by Stripe. 1c3d never sees your card number.
Where your $4 goes
Everything on 1c3d is free to read, and it stays that way. There's no company behind it and no investors, so the bills and the build time come out of my own pocket, with a little help from affiliate links.
Pro subscriptions go straight back into the site: keeping it fast and online, and buying the time to write and test new guides, add calculators, and keep improving Comms, Asset Manager and the Print Farm game. If 1c3d has saved you a failed print or an afternoon of searching, this is the easiest way to say thanks.

Questions
How do I cancel?
Come back to this page and choose Manage billing. Cancelling stops the next renewal, and you keep Pro until the end of the period you already paid for.
I pay for Asset Manager Pro. Do I need this too?
No. Asset Manager Pro includes 1c3d Pro. Use the same email address for both accounts and verify it, and your badge and perks turn on by themselves.
I have 1c3d Pro and want Asset Manager Pro. Will I pay twice?
No. When you upgrade Asset Manager with the same verified email, you get $4 off your first payment, and your separate 1c3d Pro billing stops on its own. Your badge and perks carry on without a gap.
Do members still get no ads?
Yes. Signed-in members don't see ads, Pro or not. Pro is about supporting the site and getting the extras above.
What happens to my saved results if I stop Pro?
Nothing is deleted right away. Your limits go back to your rank's numbers, and older saved results above that number are trimmed the next time you save a new one.
Can I get a refund?
Partial periods aren't refunded unless the law requires it. If something went wrong with a charge, get in touch and I'll sort it out.
