Affiliate Disclosure

Last updated: June 30, 2026

Affiliate Relationships

SpoolMath participates in affiliate advertising programs, including the Amazon Associates Program. When you click an affiliate link on this site and make a qualifying purchase, we may earn a small commission — at no additional cost to you. This helps keep SpoolMath free.

As an Amazon Associate I earn from qualifying purchases.

Amazon Associates Program

SpoolMath is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.

Calculator Estimates Disclaimer

All calculator outputs on SpoolMath are estimates only. Filament prices, electricity rates, and print times vary. Results are provided for informational and planning purposes and should not be treated as financial advice. Always verify current prices before purchasing.

Editorial Independence

Affiliate relationships do not influence our editorial recommendations. We only link to products we believe are genuinely useful to 3D printing hobbyists. Affiliate commission potential does not determine which products are mentioned or recommended.

Other Affiliate Programs

In addition to Amazon Associates, SpoolMath may participate in other affiliate programs (such as filament or printer brand programs). Any page carrying affiliate links will show a disclosure notice. This page serves as the primary FTC disclosure document for the site.
