These are some modifications you can use for 1/4 inch vinyl tubing. The tube holder is used to keep the tube straight rather than curling up since it comes in a spool. The tube splitter is a junction for 3 of the 1/4 inch tubes. It should be (mostly) watertight (some hot glue may be necessary). The parts have a flat bottom for the purpose of printing.
