X carriage M90 Fan
thingiverse
To enhance cooling in Mendel90's Hotend, I added a fan using the one from hotends.com. Due to the shorter MKV-B, proper airflow to the upper PEEK part was challenging without adding extra parts. This modification is designed for Nophead's sturdy version (10mm smooth rods, 60mm apart). If needed, I can provide files for an 8mm rod version. The fan works well with Black PLA but ABS could be a better choice due to temperature. It is compatible with T2.5, T5 or other timing belts. Additional strapping parts from Nophead's files can be used. Fans are available from Asus' site or elsewhere. A lid was added to prevent hot air from the hotbed reaching the fan, ensuring colder air from the top of the carriage and improved airflow.
