2018-06-18 - See https://www.thingiverse.com/thing:2967526 for newest v7 model. Different tubes, shorter print time. This is the same as V2 except it is intended to fit fully within a 4" pipe. If you have trouble printing without micro-leaks, this will allow you to fully encapsulate it within the 4" pipe. I intend to put it fully within a clear pipe so that the holes will be easy to see to drill. It will probably be a tight fit. For the original V2, go here http://www.thingiverse.com/thing:1593815 2016-06-03 - Updated file to make top diameter 1.5mm smaller to better fit ID of 4" pipe. 2017-09-04 - New version that cuts out some of the center to reduce print time / material. Shouldn't have any negative effect on function. This version is designed to correct a few printing related deficiencies. No more bridging Hollowed from the bottom. If the print isn't completely water tight, this can be filled in with some kind of filler to seal the tubes. I'm hoping this to be easier to seal up if there is any printing related leaks. Removed a lot of excess area to save print time and plastic. Issues I have been having with printing: Several micro leaks between layers. Leaks very slowly. If you know how to print without leaks or a suitable and inexpensive way to plug leaks, please let me know. A cell housing for 7 tubes for a water fuel cell. I designed it to be size compatible with 4" inner diameter clear pipe. Tubes it is designed for: Outer diameter of outer tube 1" Outer diameter of inner tube 3/4" Outer tube is 77mm long. Inner tube is 90mm long. These are NOT the dimensions of Stan Meyer's tubes! I make no claims whatsoever as to effectiveness, fit or suitability. This is here simply for interest sake. I recommend having wall thickness >1mm when printing. The holes for the contacts are 5mm in diameter, to be tapped for M6 screws. I have also made some nicer caps.
