OB1.4 Y-motor fan upgrade

thingiverse

I have been printing 24 hours a day recently and the Y motor has been overheating so this upgrade part uses a cheapo VGA fan to cool the motor - works extremely well. This part works with both the OB1 and OB1.4 printers. This example was printed with a broken Y-motor mount hence the poor print quality. Instructions Print it out at .25mm layer height and 40% fill or better. Search Ebay for "VGA fan" and you'll find one of these for about a dollar each normally. Connect it straight onto the 12 volt terminals from your power supply.
