Dust off your 3D printers, it's time to make some fish. This will be a support video for those who would like to print their own fry tray.
Print files are currently available as part of a new channel Patreon. This page (before subscribing) will provide some additional details to consider before attempting to print one of these. Link below:

For those without access to a 3D printer, full fry tray kits are available here (Currently US only):

I know I will be asked about specific products, so I'll provide links to what I have used. All of the below will be Amazon affiliate links, which means I may earn a commission if you buy the linked product. Please avoid any impulse purchases here. Do some reading first and consider what is already available to you. If you have never 3D printed before and this project inspires you to start, I would recommend practicing on simpler parts before attempting to print the ones shown here.

Now, an idea since you enjoy designing. Keep the upflow, keep the hinges. Make it deeper and less wide. Opposite corner should have its own 'pipe' that have an inlet few inches above the bottom. This will be an overflow, always. The other two corners should be designed for a transparent PVC or acrylic pipe that keeps it fairly water tight. Then push down purple LED into these pipes. Create a 'refugium' that is always producing light. Duckweed at the surface to keep light from spreading and filtering the water nutrients. Raise Daphnia inside the box. The daphnia that get too close to the inlet, gets swept into the tank. Cyclops and Daphnia, raised inside the tank. All four sides will have a 'rougher' surface to attach Java Moss and allow Algae growth. Essentially, a tank to grow a live feed without fish or otherwise, destroying the reproducing ground. While allowing mulm to collect at the bottom of the tray to a degree. While Duckweed block lights and the unsightly aspects of mulm. The of course, algae booming. Creating a natural filter.

I wonder to what extent this "mild personality disorder" correlates with just another case of ASD & ADHD... I recently saw Dean's fry system and of course immediately tried to improve on that in various way even though I only re-entered the hobby two months ago after about 20 years and got my first fish four weeks ago. First fry are already swimming. I don't have a 3D printer but must say your design seems great and a further improvement in what I came up with. Will see if I can tinker with it some more. Thanks for putting in the energy (although your brain was probably pushing you to go there anyway 😂) and sharing it with the community!

Some amount of full fry tray kits will be available (currently US only) for sale here: www.etsy.com/shop/makemorefish 5/22/23 Added to alternative core components: Main Body variants with total lengths between 7 and 11 inches 5/27/23 Added to alternative core components: Uplift Tube variant that connects to airline tubing without an elbow or other connector 6/8/23 Added two additional rigid tube mounts with a slightly wider opening to accommodate variations in the outside diameter of 3/16 rigid tubes. 0.205 is the diameter shown in the support video. 7/2/23 Adjusted the main body female threads to print more smoothly. Uplift tube threads rotated -50 degrees to match Lowered the position of uplift perforations to expose some inner channels that could potentially clog after extended use Increased the downward slope radius of the two channels where water leaves the air uplift Lowered the bottom of the outflow ports by 0.05" to expose more foam and further reduce flow concentration Extended or otherwise reinforced the rail clip prongs of the rigid tube mounts Added a main body variant (standard length) with no air uplift system, for those with separate water supplies Exported STL files with a higher level of refinement to reduce tessellation of the larger radii. Should also improve thread quality Moved the airline only uplift to the core components file. Tubes meant to attach airline fittings are now in the alternative core components file.

Hi, very interesting. What kind of material do you use/recommand? I have printed some mossgrids with a suctioncup but they got so brittel that the fell apart, that was my experience with PLA. I would recommand avoiding round holes in the uplift tube, think more in the shapes of an rhombus or an honeycomb, so you can better controll the overhang in the printing process and get better results.

Hi, quick question. I signed up for the membership and printed two units. They came out great. I used an Ender 3 with PLA and the default Cura settings for the printer. Both are in use, but I just pulled out the first one and I notice the air uplift chamber that is part of the main body, filled with water. I cannot see any hole that would allow water in. I assume there has to be otherwise I don't see any way that water could enter. Do you have any suggestions? I'll check the second unit when I pull it out as well.

@MakeMoreFish 9 ай бұрын

There could be very small holes letting water in. It's very difficult to 3D print an object that is 100% watertight. PLA is also hygroscopic so it will absorb water and exchange humidity into the hollow interior chambers which could later condense back into liquid water. One way or another, the parts are slightly and slowly permeable. You can try ABS or PETG, those I don't think are as absorbent but still would be tough to make 100% watertight. This has happened to me many times and I can't say there has been any negative impact as a result.

@chrisvan667 9 ай бұрын

@@MakeMoreFish thanks for the input! I'm thinking that if there's no negative effects, no reason to print another one with PETG. I suppose my only remaining concern would be if, overtime, water inside the chambers gets stagnant and leaks out. Seems unlikely though.

I don't use supports. The main body should be printable on an ender but you might have to rotate it so the length runs along the X axis. Maybe adjust the margins too.

I would like to outsource the manufacture to someone who has access to a Creality Ender 3 Neo Max 3d. Can you offer advice regarding printing time and material requirements? Thx!

@MakeMoreFish 4 ай бұрын

For print time, if you're thinking of print settings, I always recommend printing at a relatively slow speed. Modern printers are capable of printing at high speeds but the limiting factor in print speed, as I understand it, has always been properties of the materials rather than the machines doing the printing. Those materials haven't changed so I stick with old wisdom. I print between 20-30mm/s and only go higher for travel and infill. That ends up taking several days to print all the parts. For material I would say that depends on your access to a printer. If you have consistent access, I would use a PLA + / PLA pro. It is a very easy material to work with but (may) degrade in water over long periods. More on the order of years than months, but it's still something you should be aware of. If you want to make something longer lasting, I would go with PETG. It's a pain to print but totally possible on Creality printers.
