Up Date to my Dual Extuder and Fans
pinshape
As with my previous one, this one also relies on just one fan, ensuring ample airflow. I opted for the 5-volt fan found at http://www.amazon.com/gp/product/B00EL938E6?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00 for around $11.00, which can easily be powered by 12 volts without any issues. After using this setup for over seven months, I haven't experienced any problems. To make the most of it, I strongly recommend incorporating a variable voltage regulator to adjust the fan's speed according to your needs in real-time. For this purpose, I utilized the LM317T, available at http://www.amazon.com/gp/product/B00AUECKR2?keywords=lm317t+voltage+regulator&qid=1447775526&ref_=sr_1_2&sr=8-2, which can be purchased in packs of ten for approximately $6.00 and is surprisingly easy to assemble using Design Spark Mechanical from http://www.rs-online.com/designspark/electronics/eng/page/mechanical. Have a fantastic day!
