Ringing Bell

myminifactory

Bells really need to be made of metal to ring, but surprisingly, this one-piece print does a great job thanks to its shape, internal space, and clapper movement. The fact is it resonates, so it has a tone. If you hold the sides instead of the top, the sound changes. The clapper causes the bell surface to vibrate or resonate, generating a note or tone, which means you can argue that it rings and isn't just a rattle. You be the judge by printing one for fun. The clapper builds up separately from the body with its shaft expanding at the top to prevent it from coming out; when printed on a precise machine set up properly, the clapper should swing freely in all directions. The walls of the bell are thin, so it doesn't consume much filament. However, using high infill will increase the weight of the clapper and help it ring better. Two shells with 50% or more infill (PLA) is recommended. Using a raft is recommended because it allows the print to be removed from the build plate gently, reducing the risk of damaging the clapper as the raft can then be removed gently instead of pulling the print directly off the build plate without protection for the clapper. A small waste ring has been included in the design so the raft should extend across the entire base of the bell; otherwise, some raft will form under the bell and a separate section under the clapper, so the raft won't achieve the desired result of gentle or easier print removal. This Ringing Bell is a unique shape with a hanger on top. This fun, novelty print can be used simply to create noise from a 3D printed thing or as a decoration at Christmas and other special occasions.
