Become a Supporter

Keep the lights on, unlock the AI designer & unlimited lithophanes

Everything here is built & hosted by one person. The photo generators and the 3D designer stay free to use with a free account — building, previewing and editing are never limited, and there are a few downloads a day to take home. Supporters lift the daily caps and unlock the AI model generator, which costs real money every time it runs.

How Supporter access works
  1. Register & log in first — that's the account your Supporter access lands on.
  2. Subscribe with the button above. Checkout is handled by Payhip (our payment provider), who take card or PayPal. We never see or store your card details. Please pay with the same email as your account.
  3. Your access unlocks automatically, normally within a minute of paying. It stays on for as long as your subscription is active, and renews per month.
  4. Cancel whenever you like — you keep Supporter access until the end of the period you've already paid for.
  5. Prefer a one-off gift instead? The donate page takes PayPal or WeChat Pay. Questions: contact@3d-lithophane.com.

Supporter renews per month until you cancel, which you can do at any time. Payments are processed by Payhip, who act as the merchant of record and handle any VAT or sales tax; your card details never touch this site.
