Radial cooler for ultimker original.
Printed in 3 pieces and joined together with superglue.
Primarily made to learn more about free-form shapes in FreeCAD.
Print the cooler in ABS for higher thermal resistance.
I melted my first PLA cooler in some areas while printing with higher ABS temperatures.
To avoid melting, turn on the fan (low speed) to cool down the cooler himself with fresh air (even for printing ABS).
