The cost of an infill 3D model for Etsy sellers generally ranges from $5 to $50, based on complexity, file type, and designer experience.
- Simple infill patterns (grid, honeycomb) with standard STL files are cheaper ($5–$15). - Custom, strength-optimized infills (like gyroids) or seller-specific formats cost more ($20–$50).
If you’re new, start with pre-designed infill models on Etsy to test demand before investing in custom work.
