Ender 3 Pro, 5015x2 options. This picture is printed with stock ender 3 pro. Printed with Supports, 50% infill and this one was .16mm layer height. Amazon basics PET-G, 100% fans. Reprinted later on with 30% fans(with this duct installed and 2x 5015s) and it is MUCH stronger. PET-G likes it hot. so if you want it too look good and be strong still, 30-50% fans seems ideal from my tests with the dual 5015 fans
Amazon Basics PET-G
Printed with skirt to clear nozzle. nice and slow 50mm/s. .16mm layer height. printed a second one due to cracking on fan wall support at .12mm and it came out MUCH stronger and cleaner.
