About this 3D model

Spacers for the mounting tabs on a 4010 blower fan. These are placed in the recess on the back side of the mounting holes to prevent the screws from flexing / breaking the tabs. At 0.8mm thick, the spacers hold the fan slightly off the surface. Scale down in the Z axis a bit if you want the fan to sit flush. Since these are very small would print a batch to allow more cooling between layers.
