Nema 17 cooler for 50mm fan
thingiverse
This cover shields a NEMA 17 motor and diverts the air from a 50mm fan over the motor to keep it cool. The motor stays unchanged and is held by friction alone. I run a quiet fan but will use a resistor to slow its speed some since it's very effective. It was crafted in DesignSpark and represents an original concept, not borrowed from any other project.
