Designed for FDM and exported at nominal size. Choosing a material changes the slicer advice we show - never the part's dimensions - so keep shrinkage compensation in your slicer's filament profile, where it's measured per spool. Clearance fits come from measured fastener and hardware tables. Snap and lipped parts assume a 0.4 mm nozzle; print 3+ perimeters for strength.
