Works out what it costs to print a part (filament, electricity, failures, machine wear, extras, marketplace fee) and how much is left per sale and per hour.

Filament (with failures)
Electricity

Marketplace fee

Left per machine hour
Shipping is not included (on Mercado Livre it is usually paid by the buyer or subsidized). Amortization is how much of the printer the part "pays off"; if the machine is for hobby use anyway, look at what is left without it. Prices are in Brazilian reais (R$).
