Calculate a uniform model scale
Copy the current X, Y, and Z dimensions from your slicer, choose the dimension you need, and enter the target size. The calculator gives you one percentage to use with uniform scaling enabled.

Keep uniform scaling or the linked-axis control enabled in your slicer, then enter the calculated percentage.
The cubic volume factor describes ideal geometry only. It does not predict exact filament use or print time because wall count, infill, supports, layer height, and slicer behavior also matter. Re-slice and check the final build-volume fit, material estimate, and small-feature thickness before printing.
