Supra-sopranino recorder (garklein)

I reproduced this  from Adrian Brown's Modena supra-sopranino PDF. 

In order to print, I suggest having each section mostly vertical - you can print up to 10deg off vertical without negatively affecting the barrel. Do note, this is a resin print in order to properly print the labium (the air blade at the whistle part).

This prints completely in 1 piece. However, the intonation is VERY harsh, and was deemed in the documentation as nearly unplayable. 

For safety, you can also use a medical grade epoxy thinly covering the mouthpiece. https://atomadhesives.com/aa-bond-fda15-food-drug-administration-medical-grade-epoxy-adhesive/ is a good choice. It's expensive though.
