Simple Coloured Beer Line Markers

I wanted some simple coloured beer lines, These would be a tight sliding fit over the different size beer line I use, so that they do not slide back and forth under gravity.

This is simple to achieve using the modern slicers, where you can create simple cylinder volumes. One is use to be the print with another as the modifier to be the hole in the centre.

The the diameters are not what you need for your line you should be able to reconfigure them in your slicer before printing.
