I did some changes in the scad... wall thickness: t=1.05, trumped dimensions: ty1=ty0+211 and also added a little cylinder to support the trumpet, once printed, I removed the cylinder with pliers.
Height of the thing: 237mm (cupcake cnc aka bot1334 +
few of my things
It took 1h10' @ 26mm/s, 0.34 layer height, Flowrate: 212.5
Unfortunatelly I forgot to check Travel Feedrate, 50mm/s, which I should have lowered to match the extrusion Feedrate.
looks like thingiverse is a little bit lazy to show the picture :'( I try to add it here :-P
