Project overview
This project is a PHP + MySQL web system designed to make cost calculation, quoting and delivery workflows more measurable for people or small businesses offering 3D printing services. The initial idea was a practical calculator for filament, electricity, print time, labor, overhead, risk/waste, profit margin, commission, VAT and shipping. Over time it evolved into a broader operating panel with quote archives, customer cards, mini CRM, delivery confirmation, revision messaging, production tracking, notifications, monthly business reports, quote conversion analytics, QR links and plan-based feature control.
The architecture intentionally avoids framework dependency so the system can run on cPanel/shared hosting with a clean file structure. The implementation includes an installer, controlled migrations, SEO-friendly URLs, dark/light theme support, session-based membership, admin role protection, notification archives and cron-compatible background tasks. Internal cost and profit details stay inside the user panel while the customer-facing quote view remains simple, showing only the payable total, delivery status and necessary approval steps.
Case Study
The technical story from problem to outcome
In many small 3D printing workflows, filament, electricity, machine depreciation, labor, waste, profit margin, VAT and shipping are calculated manually or tracked in separate notes. This creates pricing errors and makes it harder to deliver a consistent quote experience. Sales-after steps such as quote approval, delivery confirmation, customer feedback and monthly business visibility are also often disconnected.
The solution connects the pricing engine with quote management and customer tracking. A user can calculate with manual values or saved printer defaults, convert the result into a customer quote, share an online quote link and track approval, revision, production, shipping and delivery in one workflow. Notifications, monthly reports, plan features and mini CRM modules support the same core flow.
The technical stack is built with PHP, MySQL/MariaDB, HTML, CSS and JavaScript. Separate database structures manage migrations, user plans, admin roles, quote archives, customer cards, notifications, monthly reports and production tracking. SEO-friendly routing keeps old PHP links working while presenting cleaner URLs. Cron tasks are planned for monthly reporting, automatic delivery checks and background notifications.
The project grew from a cost form into a compact operations panel for small 3D printing services. It combines pricing, quotes, customers, delivery, notifications and reporting while keeping customer-facing pages simple and internal business metrics protected.
Architecture
Block-based system flow
Filament, print time, electricity, labor, overhead, waste, profit, VAT and shipping values.
Manual values or saved printer defaults produce quote totals and internal profit metrics.
Quote archive, customer cards, revision messages, delivery state and notifications.
Detailed internal cost screen for the owner, simplified approval flow for the customer.
Monthly business reports, conversion analysis, customer price history and satisfaction metrics.
Live showcase
Demo, output and visual story
The initial workflow was close to manual calculation and scattered quote tracking. Costs were handled separately and the approval or delivery status of a quote was not visible in one operational screen.
The current structure connects calculation, quote, revision, production tracking, delivery confirmation, customer cards, notification archive, reports and plan-based feature management inside one panel.
The calculation layer produces internal cost values, the quote module turns the result into a shareable customer record, the customer quote view shows only simplified pricing and status information, and the panel keeps business analysis available to the service owner.
The strongest output is the end-to-end path from calculation to customer quote, then to production and delivery tracking. Internal business details stay protected while the customer receives a clean quote experience.
