Pla cooling extruder started as a curiosity and it works FCStd file so you can mod it Its fully hollow, for a 30 mm fan (standard) the holes stay to the user I did them by hand (7 holes wit a 2.5mm) didn't use any bolts drilled at 2.5 it's perfect for the 3mm screws But remember its pla. used on abs didn't melt. just waiting for my turbine fan so I can change it again. 1.5mm walls so you can print easily don't forget supports and Kura is going to try to cover the fan hole.
