No Shriek Noise Printed Caliburn Stock Spacer Tubing

A stock spacer tubing for the caliburn that can be printed and doesn't make the 3d print on 3d print noise on priming that the only printed one does.

Friction fits in the printed stock spacer.

Tube is mcmaster part #8585K207, same as the caliburn plunger tube.
