Built for makers, artisans, electronics and 3D-printing hobbyists, and marketplace sellers on Etsy and beyond: stop mispricing your work in spreadsheets.
Its strength is nested bills of materials (BOM) with real costing. If you have 1 kg of PLA and a part uses 30 g (about 1 oz), Favo counts only the fraction you used β€” and adds your labor minutes and the printer's energy. So the cost is the real one, not a rough guess. And when a supplier's price changes, your average material cost updates by itself.
