About this model

Choose a fan frame size (40–140 mm), a style (flat mount plate, concentric-ring finger guard, or size adapter between two fan sizes), and a plate thickness. Mounting holes are sized for M4 screws with a clearance fit. Prints flat on the build plate, no supports required.

Built for an easy print

Prints support-free in the orientation it downloads in - an automated gate checks every model on every change.
Meshes are verified watertight before they ship.

Print settings

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.
