Ultimate Cooler for Nema 17 Stepper motor for 30/40mm fan

thingiverse

Hello, I have some printers and have a major issue in summer : many of them have overheating motors, first I check the current, but all was good, so I decided to design a nema 17 stepper motor cooler for an efficient and perfect cooling ith easy setup Before print, read print settings ! Here are the most important features of my work : -for all Nema17 stepper motors (42mm sides) bigger than 40mm (40, 48, 60 : nearly all printers) -40mm OR 30mm fan (will make radial fan model too if you want) -fit on the back of the motor : nearly all steppers have free space to fit this -printed in 2 parts : no need to unmount the stepper motor, no need to unplug (you can nearly install them in plus and play mode when printing :) ) -efficient cooling with the baffles that I made -cool the sides and the rear of the motor -easy to print, just set 100% infill and support for higher angle than 70° -in my case, drop down the temperature from 58°C to 35°C (136°F to 95°F) on a 4hour print ! (no more stepper skip or overheat !) -M3 screws (10 or 12mm) to hold the 40mm fan -just print, fit on the stepper motor, mount the fan, and go ! Please like if you download and think to post your made one I really want to see other people prints too :) And one more thing to ask guys, If you really love my works, please feel free to like my page, it help me a LOT : https://www.facebook.com/Zoltan3D/ BIG THANKS
