Tuning Fork Model

I originally wanted to try making a tuning fork experimental equipment that could be used, but the results of the experiment failed. Due to the insufficient rigidity of PLA material, vibration attenuation is very fast, elastic modulus is low, and vibration mode is unstable, making it difficult to achieve the same effect as metal tuning forks.Therefore, I have made slight adjustments to this model, which is only used as a visual model and does not have real functionality. I reduced the filling rate (5% only) to minimize the usage of PLA. If you are interested in this, I can share my STL file and you are welcome to continue trying.* During my testing, I set the filling rate of the tuning fork section to 85% and 2 layers of wall.
