Dough Guard Aucma Stand Mixer

Recently an Aucma Stand Mixer entered the fleet of gadgetry. No Internet connectivity, so you are probably not clear on where I’m going with this, but… hack on!

You see, the Acuma stand mixer (like others) has a bit of a problem with Dough climbing up the kneeding hook. Drop a bunch of flour, some yeast, salt, a bit of water in a bowl, hit the go button, and after about 10 minutes the dough is wandering up around the top enroute to the door.

This must have a simple solution involing 3D printing, right? Well, a few lines of OpenSCAD and it does look like it. Open up the micrometer, measure up the dough hook, come up with this script:

OD = 27.75;
ID = 24.75;
NOTCH_WIDTH = 2.5;
WIDTH = 35;
HEIGHT = 7;
difference() {
 difference(){
  cylinder(r = OD/2, h = HEIGHT);
  cylinder(r = ID/2, h = HEIGHT); 
 } 
 cube(size = [OD*2, NOTCH_WIDTH, HEIGHT*2], center=true);
}
difference() {
 cylinder(r = WIDTH-1, r2=WIDTH, h = 3);
 cylinder(r = OD/2, h = 3);
}

and we get a shield that looks like below.
