This little powerhouse knows how to produce a sound that will scare you.
Very easy printing. All parts can be printed without support.
I printed them with 0.4 nozzle and 0.2 layer thickness and 15% infill.
For the small horn I used a brim of 2mm, but it can be printed without brim.
Print all as positioned in the STL’s.
Simple assembly without glue or rubber bands.
