There
are two versions. One has buttresses behind the horns to support
printing without added supports. I've printed both with & without
supports and they both are functional. The buttresses seem to keep the
back of the horns clean. I painted them with acetone to bond the layers
and dress it up a bit.
My printer settings for this were:
0.4mm nozzle
0.3mm layer height
3 perimeters
40% infill
3mm brim
Hung with drywall screws but you could use other anchors depending on your wall and confidence.
This is an exceptional stylized piece. I really like it, it almost makes me want to learn how to play the Ukulele. What software did you use to design it? Nice work!
