Air raid siren modification ( longer rundown )

• I edited one of the siren's gears to add an option of inserting three 22mm bearings.
• Use my 3mf file to get the perfect slicing.( higher infill on the sides of the gear)

Here is the original design + the place to get all the other files https://www.thingiverse.com/thing:1176646 except for the SirHa_Getriebe3.stl file.
