Hello everyone,

Besides my Bambu Lab, I have aquaristics as a hobby

I am an aquarist through and through, and thanks to my 3D Printer, I can simplify the underwater world a bit

I have already designed two other versions of the water change diffuser, which can either be filled manually with a container (for example, a bottle) or directly with a normal aquarium hose (in different sizes). You can find these models here:

You can also find a few other things for the aquarium from me. Check out my profile

I was annoyed that the substrate always gets stirred up during a water change. I used to hold my hand in front of it so that the stream was somewhat weakened

Especially in aquascaping with smaller aquariums and fine, perhaps freshly planted substrate, it is important not to stir up the substrate, or not too much, during a water change

So I sat down at Fusion 360 and designed something that should solve exactly this problem in any aquarium

My "Water change Diffuser direct for Quick Connect" prevents exactly that

I modified my V 1 model with a ¾ inch standard thread so that a conventional quick connector with a ¾ inch standard thread from garden accessories fits on it. Now the water can flow in directly via the garden hose. Hence the name "Water change Diffuser direct for Quick Connect"

The water jet from the hose flows automatically through the connector into my diffuser, which resembles a gas pump nozzle, and is broken up by the many small, laterally arranged outlet ports. This creates a very gentle rain in the aquarium

The water can only flow out laterally from the diffuser and not directly downwards, so no jet is directed at the substrate. Consequently, there will be no stirring up

Start by carefully dosing the water jet and get used to the horizontal water outflow

Do you need a different thread size? Send me a message and I'll take care of it

Of course, I also chose the proven fastening method with the screw here, so that the "Water change direct" can be flexibly adapted to any glass thickness

My Corydoras were very happy about it recently. The fish really like the simulated rain, and it also stimulates spawning

So, refilling the water with the diffuser can realistically simulate rain for the aquarium

The diffuser consists of 2 parts:

• the Water change direct Quick Connect ¾ inch in gas pump look
• Screw

I have printed several prototypes regarding the orientations and support. The version uploaded here is, for me, the one with the best result

The auto-support added a brim to prevent possible adhesion problems on the printing plate

! If you have problems with the support structures, please note the advice from user “lewis_hill” in my comments; he advises not to print via the app and to switch the support to “tree slim”!

I myself printed on the Cool Plate SuperTrack on a P1S with PLA Basic. The brim may need some deburring and smoothing

Please remove the tree supports very carefully to avoid any damage to the structure

I deliberately chose 100% Infill to ensure the best stability, and also so that it doesn't float when the tank is almost full. You can also try with less Infill; that saves time and filament - decide for yourself

However, my fantastic results only refer to my original print profile

Please note that the first time you screw in the screw into the thread, it might be a bit stiff, but that will ease up immediately

I have already given a prototype to aquarist friends and asked them to test it. The feedback was positive, and the effort seems to have paid off

This diffuser is a relief for every water change, and the inhabitants of the aquarium enjoy the gentle rain

From my experience, this method is the easiest, safest, most convenient, and fastest way to fill fresh water into the aquarium. Make sure the water does not overflow if you do not supervise the inlet

Connected to a tap, you have both hands free, and the water flows in by itself

Thus, it is also ideal for larger aquariums

I hope I can simplify your water changes a bit with this as well

Continue to enjoy your underwater world and the 3D Printer
