Experimental Ocarina

prusaprinters

The intention of this experimental Ocarina design was to try to improve the fipple to make the upper notes work better right off the print bed before sanding. I guess you might call this a work in progress mainly because it needs some additional analysis regarding the changes I made to the original to see if they are better or not. It has been nearly a month since I worked on this and so I forget some details after I printed it but I recall it was pretty good but still needed some sanding. I tried to improve the fipple design. Did it work? Maybe. Was it revolutionary? I don't think so. I've been going back and forth on whether to post this or not because it is unclear to me if it is better but decided to post because others might also like to experiment. This is a complete design within Fusion 360. This time, I didn't hack a mesh to add my changes. I went to the original source shared by the original designer ( https://www.thingiverse.com/thing:883182 ) and converted it to a STEP file, then compared the original source with the differences made in the stl file from the fipple remix that made the upper notes work better (https://www.thingiverse.com/thing:2755765 ). I also added a 45 degree integrated curved mouth piece, then modified the fipple even further by moving it slightly further into the windway and making it a sharper point... Not sure if my changes negatively affected the tuning or not but I suspect not in a meaningful way. I also rounded the ends of the windway as I read somewhere that it gives an experienced player more control. I'm not sure what effect it has in this case though since the windway is long and curved. I did print it and a few upper noted did work slightly better of the bed for me but that may just have been a coincidence. I haven't analyzed if it is truly better or if I just got lucky. How well it works off the bed is really more a function of the printer's ability to create a sharp labium edge I think. I printed at 0.28 layer height and this did need some sanding of the labium edge. I've included a matching sanding tool design right here for that also. I like printing with a flat bottom for easy printing and so it stands up on its own so I cut off the end but left the end cap I cut off in case some would prefer to superglue it back on. The result will be nicer either way than using a raft. The changes I made should be relatively easy to compare because I superimposed the original fipple remix mesh so it can be seen exactly what I did to it in Fusion 360. You can see it in the screenshots too. Does this supersede my earlier version with the integrated 45 degree curved mouthpiece (https://www.thingiverse.com/thing:4689924 )? It's tough to say. It probably doesn't matter really because they both will require a little sanding to make all the high notes work. Are my changes valid?... I am not certain which is why I am calling it experimental. If I was to experiment further, I would base further efforts on this effort though and use Fusion 360. If you experiment with this, be sure to let us know if you discover anything. Thanks to every designer that has been involved with creation of the Ocarina thus far! Enjoy!
