Steam Train Whistle
by MikeP-NZ, published
This is a 3D printed version of a wooden novelty toy that belonged to my son's friend. The sound it makes is unique with the 2 notes combining perfectly.
This working prototype was printed on a RepRap Prusa-Mendel It2.
Sliced with Slic3r 0.9.9
nozzle dia 0.35mm
3 layers top and bottom
0.25 (25%) fill at 45Â° with solid fill threshold set at 5 sq.mm.
The print time was 65 minutes and it took 14.7 cm3 of PLA.
That's 2.4m of 3mm filament.
