Goblin - Plunger & Front for 38mm OD x 35mm ID Tube

I was graciously gifted a plunger tube. However, it didn't match exactly the suggested 1 ½" OD 1 3/8" ID tube. Instead, it was 38mm OD and 35mm ID. To adapt for this, I enlarged the O-ring areas on the plunger & front so that it would seal. For my personal build, I added 2-3 rounds of plumber's tape but you may not need to. For the plunger, I added an extra -123 O-ring. Print Settings: Use same print settings as the original. Assembly: All is the same as the original, except you can add an extra O-ring to the plunger.
