Silencer/Moderator Adaptor - two part

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.

• Print the adaptor part (Adapter.stl) on the flat side (as it appears in the slicer), no supports, no brims.

• Print the insert part (Insert .stl) on it's side (as it appears in the slicer),use supports (touching buildplate only), and a brim.

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

1/2-20 UNF threads as is airgun standard.

Print the adaptor part (Adapter.stl) on the flat side with no supports and no rafts. Ideally 0.2mm layer height.

Print the insert part (Insert .stl) on it's side with supports (touching buildplate only), and a brim. Ideally 0.12mm-0.2mm layer height, I used 0.2mm.
