About this 3D model

This is a silencer for the Daisy 880 air rifle.Not the noisiest air rifle in the first place, but I was keen to see how low it could go. While the rifle definitely sounds different -less of a PAH, more of a peh-, the attached dB graph image shows mixed results. It's definitely quieter when pumping 5 pumps or higher, but is a bit all over the place below 5 pumps. At a friend's suggestion, I made the baffle parts at intersecting angles in TinkerCad, because Blender's boolean operations went crazy. But in case you want to mess with it a bit, I've attached the Blender file for easier remixing.The barrel attachment is remixed from: https://www.thingiverse.com/thing:1873585
