The filament, machine, and electricity lines already include the 10% failed-attempt allowance, which adds $0.04 to this job. Fees use the calculator's typical Etsy profile (9.5% + $0.25); other fields are the calculator's defaults. Computed with the same calculateJob function as the calculator.

Assumptions behind this example
This example keeps the calculator's default $24/kg PLA, $0.20/kWh electricity, $30/hour labor, $800 printer amortized over 4,000 hours, 10% failure rate, and $10 combined packaging/shipping/overhead, changing only this part's grams, print hours, and finishing time. Your own material, printer, local electricity rate, and failure rate will change the result; open the calculator to use them.
