Digital & Print-on-Demand: see your true cost
This is the actual Anvil HUD pricing engine running on researched preset numbers, set up as a digital file (an STL, SVG, or pattern) sold on a marketplace. Move a number and watch the price move. No account, nothing stored.
A file has no per-unit material, so the engine amortizes your design time over the sales you expect and leads with break-even.
Every other number (machine, rates, fees) rides on the same presets a new workbench starts with. Sign in to use yours.
What you are looking at
- The same formula the app runs: raw cost, times failure buffer and overhead, solved so the marketplace cut cannot eat your margin. Every line is published at /the-math.
- The presets are researched 2026 US figures, cited at /sources. A new workbench starts with exactly these and you tune everything to your shop.
- Signing in swaps the presets for your real machines, materials, rates, and fee profiles, and lets you save products, log jobs, and learn your true failure rate.
Make it your number
The demo prices a preset shop. Your spool price, your wage, your fees: that is the number that matters, and the engine is free.
