34 Apparently it is possible to have comparatively tight and well fitting
35 test tube cap even from hard (PLA) materials.

39 Idea is to have outer/entrance radius slightly larger than test tube
40 and inner radius slightly smaller. Internal cap radius keeps gradually
41 decreasing. This provides tight fit.
