Sound moderator/Silencer/Suppressor adaptor for airgun. 2 pieces.
Requires 4 x M3 x 28mm (or longer) bolts and nuts.
To assemble, put the insert (Insert.stl) part into the adaptor part (Adapter.stl). Once tight and secure, put onto the barrel, and screw the 4 M3 bolts and nuts on.
Due to the tight fit, I ended up needing to lightly tap the insert in with a 15mm pipe and hammer to get it secure, and it definitely felt properly secure. It's a pretty good friction fit.
Assembly with a drop of superglue could work. The friction between the two parts is great enough I feel comfortable using it without.
Included are F360 files. The barrel width is parameterised (barrelWidth) so you should be able to change it easy to fit your own barrel - go to Modify > Change Parameters> Sketch1 > barrelWidth.
All files are available as one download - "all files.zip.stl". Download it and rename it to "all files.zip".
Measure your barrel well before you print anything, so you definitely get the correct width for you. I didn't have callipers so printed out a sheet with round holes of varying sizes incrementing by .5mm each time to get the diameter. This is also a good idea since your printer is likely slightly out from actual distances, therefore this would give you a good idea of what you should be printing even if callipers tell you a good number. I've included the hole size measuring file I made, hole sizer.stl
