You don't have a Windows PC, or want to size parts on your phone at the workbench.
You bought STL files made for a different body and want a resized, printable file quickly.
You build in EVA foam and want flat 1:1 patterns from the same model.

If you want to visually fit pieces on a full-body avatar on a Windows desktop, Armorsmith is a proven choice with many community tutorials.

Every fit is an estimate. Always verify with a tape measure and a test print or test cut before printing the full piece.
