The openingWhy this idea is overlooked
Print bureaus quietly bleed hours fixing clients' broken STL files for free, and few realize that file repair and print-prep is a standalone, near-zero-cost service with software-level margins. It hides because bureaus fold it into their own work rather than pricing it, and because it looks like a chore rather than a business. But it is remote, low-capital, fast to start, and directly solves a pain every bureau and every hobbyist runs into.
