* Project description
[[file:make.png]]
Apparently it is possible to have comparatively tight and well fitting
test tube cap even from hard (PLA) materials.

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