"No supports" Ocarina printed in PLA
XYZPrinting (propetary) PLA
25% with extra thick shells
As an experiment, I rotated the orientation on the build plate (as shown in the picture) - so the ocarina could be printed without any supports (since I knew I'd never be able to clean internal supports out after it printed). To stabilize it, I added wide brims where it touched the build plate - and it printed perfectly!
This ocarina came out about 120mm long and fairly thin, which is too small for someone like me with big hands to play comfortably. I tried to scale the size up to the maximum of my build plate (about 160mm cubed), but wasn't able to print that because my slicer software removed the brim around the mouth piece when I tried it. That was probably because the mouth piece end wasn't fully landed on the print bed when I'd rotated it (about -5 degrees on the y-axis), which became noticeable once I'd scaled the overall size up.
Unlike the two previous ocarinas I'd tried to print from two different designs, this one actually made sounds - very faintly if you blew into it very gently. I could even play a simple tune, but the high notes were a lot fainter than the low ones - so overall, just barely playable. I'd like to scale it up larger, since my guess is that that would help it play better too - so I may go back and try scaling it up before I rotate it, so that the scaler software would leave the necessary brim around the mouth piece end this time.
A fun design that can be printed without supports in the orientation shown in the picture. Good job!
