thingiverse

I just created ender3 pro cooling fan blades (9 blade) with openscad (https://www.thingiverse.com/thing:689564). 9 blades hub-d : 22mm propeller d: 37 mm blade height : 6mm (but default 7.15 mm seems better, mein was a bit short) winglets off shroud off blade direction -1(default) To be able to use openscad for thing:689564 you need two libraries: https://github.com/openscad/scad-utils --> extract it under openscad/libraries/scad-utils https://github.com/openscad/MCAD/tree/dev/ --> extract this under openscad/libraries/MCAD/ Ignored two warnings below and it did not effect: WARNING: len() parameter could not be converted, in file ../../../Program Files/OpenSCAD/libraries/MCAD/shapes/2Dshapes.scad, line 279 WARNING: len() parameter could not be converted, in file ../../../Program Files/OpenSCAD/libraries/MCAD/shapes/2Dshapes.scad, line 280
