I'm trying to come up with ideas of items that can be 3D printed for aquaponics. What would you like to see printed for your AP system?

Items I've thought of or come across so far...

-Automatic feeders
-IBC connector fittings
-Media guards
-Net pots
-Root guards (to be able to put fish in raft beds and protect most of the roots from being eaten)
-Automatic siphons
-Special tools (I just finished printing a wrench to tighten my bulkhead fittings since I don't have a big enough wrench)

I'm sure I've got more noted but will have to go to my computer to find them... What else can you think of that would be beneficial to 3d print?

Hi Rob,

I think a media guard like the photos with the grill just small enough to stop K1 bio media passing through and be able to fit or glue onto 50mm PVC pipe would be an asset for use in a MBBF. :think:

I've purchase quite a few foot valve screens and haven't been able to find the correct combination, to fit the PVC pipe the grill is too large and wont stop the K1, or if the grill is small enough to stop the K1, it won't fit the PVC pipe. :upset:

I hadn't posted it because I don't have my K1 yet to test with but I have designed one for that purpose. STL is attached. It uses diamonds on 45 degrees so you can print it without any kind of supports.

Although do note this is designed for 2" PVC here in America, not sure if Aussie 50mm is exactly the same or not.

Ok, give this a whirl.

Thanks LowCarbTNPer, I don't had a 3D printer but I might be able to find someone with one.

Thanks for taking the time. :thumbright:

Joblow here in the US there are 3d printing shops you can submit the stl file to online and they will tell you instantly the cost to print it then you can pay and they will print and mail it to you. I would imagine there has to be some similar there, if not I'll mail you my 3d printer you can start one and we'll split the proceeds ;)

Thanks for that Rob, I'll check and see if I can find someone here in OZ. :thumbright:

Which printer did you get Rob? This is pretty exciting. I had seen video a while back from Bigelow farms made an stl file available for his bell siphon however it looks like it may have been a fail

I can't tell as it is too early in the morning and not enough coffee to pay attention properly. Here is the predecessor to the above video where he describes how it is designed.

It must have been redesigned, because it it still for sale on his web site a year later, in both the printed form and the stl file format.

I remember seeing that brian. I think someone has knocked off his design because I saw stl files for it on thingiverse for free I think.

I bought a creality ender 3, it's nothing fancy, with all of the filament and spare parts I've bought I have about $300 into it, figured it was a cheap enough way to learn to 3d print and have a coworker who does a lot of printing using shapeways that I could potentially get my money back printing stuff for him if I figure out all the issues I've had to get better quality. I'm getting closer.

Hi Rob,

I think a small 3D printed grill to stop fingerlings swimming into the IBC outlet drain would be a great asset. Something with small barbs on it that would just push firmly into outlet hole on the inside of the IBC.

It would also allow you to slowly drain the IBC without fish being sucked hard up against the outlet.
