3D Printing Profit & Pricing System: Price every 3D print for real profit, not guesswork

Hey Product Hunt! 👋 I built the 3D Printing Profit & Pricing System after noticing how difficult it can be to answer a simple question: **“How much am I actually making on this print?”** The selling price alone doesn't tell the full story. Filament, electricity, machine time, labor, marketplace fees, packaging, and other costs can quickly eat into what looks like a healthy profit. I wanted to create one practical system that brings those numbers together and helps makers, Etsy sellers, and print farms price their work with more confidence. The goal is simple: **less guesswork, better pricing, and a clear view of the real profit behind every job.** I'd love feedback from the Product Hunt community — especially anyone running a 3D printing business. **What cost do you find the hardest to account for when pricing a 3D print?**
