Baby Air Raid Siren

I finally had time to implement the request for a children's version. For this, I modified my original Hand-Cranked Air Raid Siren model https://makerworld.com/en/models/1720857-hand-cranked-air-raid-siren#profileId-1826604 so that it should fit better in smaller hands. All parts, except for the internal gear mechanism, have been adapted to the new conditions. Since a remix by nitrokdf with suitable grilles for the big brother has just been released https://makerworld.com/en/models/2669818-siren-grill, I have also created versions with hexagonal grilles for more safety

In this model, all components are now screwed together with Ruthex M3x5.7 heat-set inserts and corresponding M3x8 screws (16 pieces each). It may be necessary or possible to screw a screw directly into the plastic, but I will go into more detail about this during assembly. The four 608ZZ bearings from the original model have been retained and are also required here. Crankshaft V2 and a revised version of the problematic handle are already included in the .3mf, there is also another version of the handle created by Patrasca https://makerworld.com/en/models/2652718-3d-print-optimized-handle-for-air-raid-siren#profileId-2932926. I am already attaching the assembly instructions, and an assembly video is also planned

I hope you have as much fun with the little brother as with the big one. If so, please leave boosts again

Enjoy

Revision 07/06/26: Modified versions of the crankshaft and the hexagonal gear added after problems occurred which could have been caused by the screw connection
