Hand-cranked Air Raid Siren

I created this remix based on the original file and an already created remix of the gears and some individual parts by Ultra Chron My thanks for the good preliminary work I only changed the layer height to 0.2mm and the infill to Gyroid and used support structures, otherwise these are the standard settings for Bambu Lab PLA Basic, used here in Bambu Green and Orange However, stronger material can also be used for the gears and shafts The fits for the ball bearing mounts and the gears have been adjusted, the shaft for the rotor has been modified so that it can be printed lying flat on the build plate and thus gains stability The through axle for the double gear was also modified due to assembly problems To better screw the rotor housing to the gearbox housing, the lower diameter of the rotor housing was changed Something about aluminum tape for fastening the gearbox housing cover was mentioned in the comments of the original file The model now has two additional screws there UltraChor has already eliminated the problems with the shafts by using square receptacles To solve problems encountered with the crank and gearbox, here is a revised version of the crankshaft, the associated gear, and the gearbox cover https://makerworld.com/de/models/1773927-crankshaft-v2-hand-operated-air-raid-siren#profileId-1905735 By popular request, the assembly instructions are now also available in English And for those who are not entirely happy with the version for child safety reasons, you can find the little sister here With hexagonal honeycomb grilles around the rotor https://makerworld.com/de/models/2677694-baby-air-raid-siren#profileId-2964951 Have fun and enjoy
