Airsoft Hex Suppressor - OTB

There's two versions, "OTB" (Over The Barrel) has the thread around the middle of the silencer and the normal version has the thread at the base.

Silencer dimensions: 157mm x 35mm
OTB: The barrel hole is 15mm and the thread starts 70mm in from the base of the can
Short version: 89mm x 35mm

Sand/file the barrel hole to fit your barrel.

Field-tested a PLA OTB version on my GBBR and it held on nicely.

The hex tube may be a pain to print if your machine is not well calibrated for retractions since this part has a big amount of those.
