Fan adapter for Rostock Max v2 to use BD5015 radial fan

thingiverse

I upgraded the original fan adapter from repables.com/r/212 to utilize a BD5015 radial fan because the standard 30x30x10 fan isn't available in Europe. Radial fans are preferred when working with a fan duct, as they can exert higher static pressure than axial fans. This leads to greater airflow despite lower nominal flow rates. With the fan at maximum capacity, my hot end peaks at only 205°C. Therefore, a single BD5015 radial fan is sufficient for this setup. I've posted characteristic curve data for your reference. To avoid ABS shrinkage while maintaining layer adhesion, I print with a fan speed of 18%. When printing PLA with three fans in use, the fan setting ranges between 65% and 70%. Instructions Use a temperature-controlled environment: Kapton bed at 85°C and a hot end set to 235°C. After achieving 2mm in height, adjust original fan to approximately 30% power.
