Someone asks for 500 of a part. What's your number? If you run production batches, you know the trap: quote from a spreadsheet, guess at the filament, add "some" for labor, pad it for nerves — and either work for free or lose the job. Every time. This guide hands you the fix. You'll build the exact batch-quoting tool I use to price my own runs — with AI, without writing a single line of code. What you'll buildA quoting tool that runs right in your browser, tuned to your shop's real costs: Reads your sliced files — drag in a .3mf and it pulls every plate's parts, print time, filament weight, and colors. No typing Prices the whole batch — filament at your real roll cost, machine time, plate fees, scrap buffer and markup — a per-unit price for any quantity Real-order costs — assembly and packing per unit, shipping, discounts, deposits, and a minimum-order floor. The fees a production run actually carries Sourced hardware — screws, magnets, feet, inserts, priced the way you buy them (whole packs), with their own markup Your true margin — not markup: what you actually keep after real spend on spools, packs, and power. Know if the job's worth it before you send the quote A production plan — how long the run takes across your printers, and a shopping list of spools and packs to buy A professional PDF quote — your logo, contact, quote number, valid-until date, deposit terms — with every internal cost hidden What's inside A step-by-step guide (PDF) — every instruction, in order An interactive version (HTML) with one-click copy buttons for every prompt 15 copy-and-paste prompts that build the whole tool, plus setup and a day-to-day playbook Why makers love it Quote in a minute — drop the file, type the quantity, send the PDF Stop under-charging — see true cost and margin before you commit to a price Private & local — runs 100% on your computer. No cloud, no logins, nothing shared. Ever No subscription — build it once, run it free, ask AI for new features whenever you want Who it's forAnyone selling 3D prints in quantity — Etsy sellers, contract print farms, product makers — who's tired of guessing prices in a spreadsheet. Beginners welcome. If you can copy, paste, and describe your costs in plain English, you can do this. What you'll needA Mac, Windows, or Linux computer, and the Claude app (building software needs a paid Claude plan, ~$20/mo). Chrome or Edge recommended. The tool you build is then free to run forever on your own machine. A note on what you'll getYour tool will look a little different from the screenshots — and that's the point. Because you describe your costs and your materials, it gets tuned to you. Same smart quoting engine, your prices. From my bench to your project. — Chris, OffDaBench
