I had built a heated enclosure for my Ender 3 S1 Pro out of an old cabinet and needed a way to mount the main circuit board outside of the heated area. I modeled this mount to hold it and position the fan for useful airflow.
Printed in ABS, 0.2mm layer height. Both pieces can be printed separately with no supports needed. Secure with your choice of #10 screws (in my case 1.5" long wood screws) through both pieces. I had some old fan screws from computer power supplies that I used to mount the fan and reused the existing circuit board screws to mount the circuit board to the base (you might want to modify this model and use a threaded insert instead)
The author marked this model as their own original creation.
