The original site had many table-based product pages, legacy checkout buttons, remote images, and mixed-language fragments. This version turns that inventory into a clear English offer with a single Gumroad checkout path.

Payment and delivery follow the BOSS888 model, with Gumroad only.
The storefront stays static and fast. Gumroad handles checkout. Cloudflare R2 stores the private zip. The post-purchase flow emails a download link after payment confirmation.
1. Upload product zip to R2
Use the verified file listed in R2_DELIVERY.md. Keep the bucket private and generate signed URLs or time-limited download URLs.
2. Connect Gumroad sale event
Use Gumroad Resource Subscriptions or a Ping-style webhook so a sale event reaches a Cloudflare Worker endpoint.
3. Worker creates the link
The Worker verifies the sale, creates a private R2 download URL, stores a fulfillment record, and sends an email with the link.
4. Buyer receives English instructions
The email should include product name, download expiry, support email, file size, and the SHA-256 checksum.
Ready-to-use CAD resources for serious drafting work.
Buy through Gumroad, then receive the private Cloudflare R2 download link after payment confirmation. The product file is intentionally not committed to this public repository.
Questions buyers usually ask.
Clear English answers reduce support work and make the international checkout feel trustworthy.
Do I receive the CAD files immediately?
After Gumroad confirms the purchase, the delivery system emails a private download link. The R2 link should be time-limited so the product zip is not publicly exposed.
Why is the product file not on GitHub?
The public GitHub repository contains the storefront only. The paid digital product is stored privately on Cloudflare R2 and delivered after payment.
Can I use the drawings directly in a project?
Use them as drafting resources and references. Always review layers, dimensions, local codes, engineering requirements, licensing, and project-specific standards before professional use.
What changed from the old site?
The old multi-page HTML shop was consolidated into an English sales page, the payment path was simplified to Gumroad, and 500tools was rewritten as an English companion directory.
