Printrbot Dual Fan Ubis 13s
thingiverse
This is a dual fan bracket designed specifically for the Printrbot, with the fan on the right connected directly to the PSU and spinning 100% of the time. This ensures the metal hotend remains cool to the touch, preventing filament from getting soft and creating jams. The fan on the left functions as the normal printrbot fan, but due to its slight offset to the left, I created a small deflector. Parts Required: 5 x 3M x 30MM bolts (use 25MM if you prefer not to use fan guards) 3 x 3M x 18MM bolts 1 x 40mm fan 1 Molex to fan adapter (available at http://www.amazon.com/Zalman-ZM-MC1-Multi-connector-Add-Fan/dp/B000FAKUE6/ref=sr_1_1?ie=UTF8&qid=1455216813&sr=8-1&keywords=molex+to+fan) Extra wire for extending the fan wire.
