For sale , for the next two weeks, starting Jan 13th
Wave Lumia tubes, 5$ each plus postage for a 2" 18 mm OD tube. You'll need to supply your own motor. No two will be alike, your choice of twist or poked. I can also fill one end with casting plastic if you need a way to make a mount that fits on a mother shaft. Larger or smaller diameters by special request.
here is a really sped up example:

Pm me if interested
