Mod for the Loud Bicycle Classic horn

thingiverse

This is a modification to the Loud Bicyle classic horn. The horn is designed so that the two speakers hangs fairly loose inside the plastic casing. My guess this is to create a proper resonace chamber for the sound, but unfortunatly in my case this allowed the speakers to move and vibrate a lot during cycling. This lead to repeated failures of the wires going to the speakers. Even though they are thick, they would simply sheer of over time because ot the movement. Therefore I printed two 5 mm thick rings in NinjaFlex to absorb the worst movements, but still alowing for some gap towards the outer casing. Also the original cusioning pad towards the bike frame didn't come with holes for the screws. I had to take the horn apart when replacing the broken wires, so I made a new 2 mm thick replacement pad in NinjaFlex with holes for the screws. Print Settings Printer Brand: LulzBot Printer: Mini Rafts: No Supports: No Resolution: 0,325 mm Infill: 20% Notes: Bottom/ top thickness: 1 mm 1 layer for the outer shell works fine. Increase layer count or the infill if you want stiffer parts. Use a PVA gluestick on the printbed before printing. Post-Printing Rings The rings are flexible so they can fairly easily be pulled over the speakers without taking apart the outer casing. Pad Attach the pad with glue or use some thin double adhesive tape.
