Solidoodle 3 X axis 40mm fan mount

thingiverse

Solidoodle's stepper motor for the X axis (NEMA14) is undersized, requiring over-driving and causing excessive heat, particularly in enclosures. To combat this, I tried using heat sinks, but they still didn't prevent motor overheating and skipped steps during long prints. Other fan mount designs were unsuitable, so I created my own. The mount fits the motor without much infill (20%), uses 3mm screws to secure a 40mm fan, and is in metric units which may need scaling by 25.4 for non-metric printers.
