14mm ccw to 20mm adapter Gel Blaster Airsoft

thingiverse

This is an adapter for attaching a muzzle suppresser or silencer with a 20mm x 1mm thread to the 14mm x1mm counter clockwise thread of a Gel Blaster or Airsoft outer barrel. Printing: I use an Ender 3 Pro Standard quality setting but you may get better results for the internal thread with the Dynamic quality setting. I use 40% infill and "initial layer horizontal expansion" (ie :Elephant Foot) set at -0.15 works for me. My suppresser is made from a piece of 25mm x 3mm aluminum tube with a 20mm x 1mm female thread tapped into it which clears the Rizer hopup.
