1/2 Scale ACA Screamer S1

This is a theoretical 1HP siren for ACA's Screamer series. Uses the core of an ACA Hurricane MKII, now as a vertical omnidirectional naturally aspirated siren. 

Probably would be a Klaxon SS6 competitor. Doubt it would be able to compete with a FS Model 2.

README:

All stls are already in the correct print orientation.  

The only parts that need to be printed with supports are the stand and the louvers.

Supports:

Overhang Angle: 80 degrees

Support type: Tree

For the rotors, use support blockers to block off the top of the rotor. 

Block all of the rotors from the middle and up.

The top of the rotor will print just fine without supports.

Cooling:

Fan Speed: 20 percent/initial fan speed 0 percent (May need to change for your printer.  Keep fan low to prevent warp)

Infill:

Rotors-
99 percent infill (lines)

All other parts-
20 percent infill (lines)

Material:

Stators-
PETG

Everything else-
PLA/PLA+

(I recommend ESUN PLA+ and ESUN PETG.  But any brand PETG and PLA/PLA+ should work just fine.)

Colors:

Rotors, stators, and top louver spacers: Grey

Everything else: Yellow

Motor:
Samsung microwave blower (dualshaft PSC ones)  These are all over ebay and can sometimes be found as low as 20$

I'm using a 250v 10uf capacitor.

Hardware:
M3x55mm machine screws (9x)

M3x45mm machine screws (3x)

M3 nut (12x)

90mm OD x 65mm ID x 5.25mm Width thrust washer (2x) ---These are the rotor weights.

Rotor installation:

Print the 5/16" tolerance tool in the same settings you will print the rotors.  Then take it and press it on your motor.  

Whichever numbered hole fits how u please, select the corresponding rotors with that hole number.

Hole 1 is 8mm, and the following holes go up by 0.1mm increments.

Once u have your rotors printed, take your weights and press them into the bottom of the rotors.  

If the outside bottom rims didn't break off already, break them off. I recommend hot gluing the weights in place to ensure they dont fall off.

Once you have the rotors pressed on, glue them in place.  U can use super glue if u want them permanent (not recommended) or u can use hot glue (recommended).

Once u have assembled the siren, you should secure the siren with tape or bolt it to a mount (M3 machine screws).

If u don't do this, the siren will spin on startup like that Screamer did at Sirencon that one year.
