Serpentine channel

11 variants

A single channel that runs back and forth so that a long path fits inside a small square. Nothing moves and there is no air line — it is a length of pipe in a compact shape.

What it is for. Buying time or resistance. A longer path means liquid spends longer in transit, which gives two streams more opportunity to blend, and it raises the pressure needed to push flow through.

Variants

Sizes below are given in px: units of the design grid these parts were drawn on, where one unit is 0.0076 mm. That is not the printer's pixel. The printer has its own, different pixel size, and nothing on this page is expressed in it — see Hardware and process.
