Cooling Extruder Motor System (New Version Updated)

Just a cooling system for the extruder motor of Prusa i3 MK3S, no glue need, but just a 40mm or 50 mm fan and four wood screws 4 mm of diameter!

Print instructions

For this project you need:

4 x Screws 4mm of diameter
1 x Fan 40 mm or 50 mm diameter
(Optional) 1 x DC-DC converter for set correct voltage of the fan

For the optional component I just used a self made board with a l7812 voltage regulator, and I connected it directly to the power supply of the prusa printer!
