M3D QuadFusion 50mm Top Fan Mount for Extruder Motor Cooling

thingiverse

Designed with 2mm walls so should be printed with 5 perimiters at 0.2mm. Should work with generic 50mm 5V fans. You will need (2x) 3 x 8mm Pan or Hex head bolts to mount to the extruder head and (2 or 4x) 3x8mm bolts and nuts to connect the fan to the mount. IMPORTANT: To mount this component you may need to disassemble the QuadFusion head and add 3mm nuts in the top mounts. Mine did not come with nuts in there. Print with minimal bed supports to ensure head mount screws have a flat surface to mount too. Otherwise you may need to manually flatten these surfaces post printing so that the fan does not catch on the bolt heads. Mount with the 90 degree divider pointing towards the back of extruder as this gives more airflow to the back extruder motors.
