So yeah wanted a fan for me SB2040 board but did not want to buy a 3010 or the 7mil version when I already had extra 4010s around. Printed with supports (this was a quick build did not invest time into making it print without supports). Watch for clearance with the z belt (front right only), mine is fine to 350mm X travel as shown in the picture. Holes for the fan are for the standard voron inserts.
The author remixed this model.
Added 4010 fan mount
