A hex-body standoff for M2-M4 hardware - wrench flats hold it steady while the screw drives in. Set across-flats and height, and choose a through-clearance bore or a self-tapping pilot at both ends.
A hex standoff sized for M2–M4 screws, with wrench flats so you can hold it steady while driving the screw instead of it spinning in place. Choose the across-flats and height, and pick whether the bore should pass a screw freely (through-clearance) or grip one by thread-forming (tap-pilot, both ends). A 1.2 mm minimum-wall constraint is enforced automatically so you can't dial in geometry that would crack under wrench torque.

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.
