3D-Printable Filament Improved Roundness For Better Extrusion Grab

thingiverse

Model based on Turbo_SunShine's 3D-printable filament, but with higher resolution that makes the section rounder. The original printed filament slips when extruded under my condition due to the hexagon section thinner than round section. Included 130mm diameter spiral which gives about 12.7g filamentIf you do a 2-pass printing for uniform color, I suggest adjust flow ratio to 1.2x your current value for both passes, otherwise under extrusion will combine and become more serious. Increasing flow ratio is also effective for one-pass printing, but either for printing filament or printing target model but not both. Mouse ear brim can be used to prevent ends from popping up from bed.
