The design was created in Onshape and can be found here.

There are several parameters that can be adjusted:

  1. tube diameter
  2. tube length
  3. tube wall thickness
  4. O-ring position and diameter of the profile
  5. O-ring size 

Explore and adjust the parameters to fit your O-ring size. The O-ring recess parameter defines how deep the O-ring will sit in the lid. Reduce/increase for a tighter/weaker seal.

Print the tube once and the lid twice. Obviously, you need two O-rings ;)

Edited: Simplified design. O-ring now sits on the outside of the tube.
