Pretty benchies don’t pay for filament. Repeatable utility parts and local demand do.
Products that tend to work
- Replacement clips, mounts, and jigs for local businesses
- Event props and small-batch merch with clear rights
- Functional organizers sized for real shelves (measure twice)
Pricing sketch
price ≈ (filament_cost × 2) + (machine_hours × rate) + design_time + margin
Track failure rate. If 1 in 5 prints fails, your real cost is higher than the slicer’s estimate.
Ops checklist
- One reliable profile per material before offering ten colors
- Written revision on every custom part
- Simple CRM even if it’s a spreadsheet
