The New Hotness

  • Makergear M2: Cushwa Owl

    You’ve seen the overview pictures of the half-scale cushwa Owl earlier, so here are some details…

    The front view:

    M2 - cushwa Owl - half scale

    The left side view:

    Owl - half size - left
    Owl – half size – left

    The conspicuous vertical lines come from the 0.10 infill honeycomb; there are no visible retraction zippers and the surface is smooth to the touch.

    A closeup of the beak shows the crystal-clear drooping filament; a similar effect happened on the downward-pointing feather tips. Generally, this is a sign of too-hot extrusion, but at 165 °C I’m not convinced that’s applicable. It may simply be too much overhang at this scale:

    Overall, it’s pretty good. The config info doesn’t include the external perimeter speed, which I’ve been dialing back from an insanely high value. I think it was 75 for this one, which might be flinging the filament off the edge of the beak below that steep overhang.

    The slic3r configuration:

    ; perimeter_speed = 100
    ; infill_speed = 300

    ; filament_diameter = 1.70
    ; extrusion_multiplier = 0.9
    ; perimeters extrusion width = 0.40mm
    ; infill extrusion width = 0.40mm
    ; first layer extrusion width = 0.39mm
    

    No source code, as it’s directly from the STL on Thingiverse.
