Bench sequence
A calculator is one step in a better pack.
Use measured inputs, treat the result as a planning specification, and verify it with production materials.
Capture the finished dimensions.
Know whether the task needs internal fit dimensions or external shipping dimensions.
Record the assumptions.
Choose the correct unit, divisor, clearance, material yield, or labor rate.
Run a physical pack test.
Confirm fit, protection, closure, movement, and the final package size at the bench.
Field notes
