About this 3D model

Fits 40x40mm fans with 32mm hole spacing, works with the Kossel end effector with 6 holes only, 60* spacing. Fan sticks down approximately 14mm from bottom of effector. No rod interference on my Kossel taking extruder to all areas of an 8"x8" heated bed. Kossel specs - 360mm frame extrusions and 288mm long rods Edit: Added STL for the effector I use.
