For a long time I had a nice bike bell with a clever design - just a single piece of plastics, easy to mount, no screws. The plastics started to wear out so I've decided to create a copy and improve the design a bit to strengthen some parts.
The design should work with any metal bike bell top. If you have a bell of different diameter, the Fusion360 file is included so you can modify it to fit your bell. Don't forget to put a piece of rubber (for example a cut from a bike tube) between the bell mount and handlebars to increase adhesion.
PETG or ASA is probably the best material for the print. PLA is too brittle, ABS is also not that good. Set the print to 5-6 perimeters.
