Daisy 880 air rifle silencer

myminifactory

This is a silencer designed specifically for the Daisy 880 air rifle. Although the air rifle itself isn't the noisiest model on the market, I was eager to see just how quiet it could be when equipped with this silencer. The sound of the rifle does change noticeably - it's less like a loud "PAH" and more like a softer "peh". A dB graph image is included below to illustrate the results. As expected, the silencer performs well when pumping the rifle five or more times, producing significantly reduced noise levels. However, the results are less consistent at lower pump counts. At my friend's suggestion, I designed the baffle parts in TinkerCad using intersecting angles, as Blender's boolean operations proved to be unreliable. For those who want to experiment with the design, I've included a copy of the original Blender file for easier modification. The barrel attachment was adapted from a pre-existing design found on Thingiverse: https://www.thingiverse.com/thing:1873585
