An air raid siren powered by a brushless motor (RCTimer 5010-360KV). It has a total weight of 440 gr. So it can be mounted on a copter.
The only part that needs support is "Sirene Rotor1".
. 2. The files "Sirene Wand" and "Sirene Deckel" are oversized. If you print it on a replicator 2 you have to cheat a little bit by moving the parts towards you (in y-axis).
RC- Stuff: an ESC with 20A,
4 screws (M3 20mm)
A bearing (5mm inside, 11mm outside, 4mm width
I already thougt About using an arduino or rasperry pi to do some kind of alarms. Should not be that hard to realize. But if you do not know what to do with this stuff ...
Rotor parts and the shell has to be as small as possible. So it is drawn quiet tight, If it is scratching on one site you have to use some sand paper.
For the rotor parts i used some glue. Put could also work by only sticking them together.
The support in part "rotor1" has to be removed very well. Otherwise it wont be running free,
I am a civil engineer. In my work i do stuff like modeling digital surfaces for excavators. Something like 3D printing in a bigger scale..
For my latest designs i use fusion 360. It's perfect for 3D printing!.Earlier designs like the siren where made with AutoCAD. Something i don't recommend for 3D printing. It's awful for 3D modeling...
I come from Austria and my native language is german. So if my words sometimes don't look right the reason for that is that i don't speak english very often.
