A fully 3d printed laundry detergent dispenser. It comes with a 100 ml cup, and you can freely adjust flow and dosage. The capacity is 2.4 L.
The designs comes with a whirl to loosen the powder and crush crumbs to prevent the mechanism from clogging up. There are two sizes of whirls provided. If the smaller one leaves a tunnel of detergent stuck inside, use the bigger one.
The file of the cup is provided with the spout on the right side, for left-handed people. If you are right-handed, mirror it in the slicer before printing.
Important: This design does not work well with natural soap products unfortunately! I have tried to make extra versions for this specific use case, but the consistency will potentially result in a tunnel formation that even the big swirl can’t help with. Regular store-bought powder works great, but very unprocessed laundry soap not.
Instructions
- Print all parts
- Place the insert onto the bottom
- Insert the shaft into the stopper. (This is a press fit, if it is too loose, use a bit of glue here)
- Place the stopper onto the insert
- Add the top
- Add your whirl onto the shaft from above
- Place the lid
Usage
- Place the cup
- Move the stopper to the left (closed)
- Fill up the top with detergent powder
- Move the stopper to the right to open and increase flow the further you push
- The cup is 100 ml when filled to the brim, refer to your detergent manufacturers packaging, your water hardness and personal preference for optimal dosage. I just eyeball it, it’s fast and convenient.
- If you notice decreased flow or a blockage, move the stopper around to crush crumbs and loosen the powder (always with the cup below)
- You have to open the lid to check how much powder is left. I did not integrate a transparent slit, because I do not expect that the average user will have transparent filament around.

Only the stopper and shaft need to be printed a little stronger, I suggest 5 walls, 30% infill and 6 top / bottom layers. For all other parts default settings are perfectly fine.
Looks great! You can support the cup to look a bit better but bridging the top is also perfectly fine!
Love it. so usefull! So pretty!
Thank you!!
Suggestion - Create a removable tray at the bottom to catch any spills.
Thanks for the input! I will put this on my improvement list!
Superb design, it works great! I think you are left handed since the cup has the point on the wrong side for me ;). I'll see if I can mirror it and print it again.
Hehe it's true! Look at the description I put a note in there that you should mirror it for right handed use. Still I am not messing with anyone on purpose here the washing machine powder input is on the left so it makes sense to make the lefty version default here
Ah! Missed that comment. Too enthousiastic when I downloaded it I wanted to print right away! Using it now for a bit and have one suggestion. Make the flippers longer. There forms a sort of tunnel in my powder. Installing the flippers after building the tower makes that they don’t need to fit through the opening! Still love the design fits my shelves perfectly + no more spills
there is finally a V 1.1 after testing took forever! Please check out the changelog!
Hey, I was searching for something handy to store our laundry detergent and really like your design! That said, I just bought your model and was a little surprised the archive only contained *.stl files. Would it be possible to also get the *.step files, since I was planning on reshaping the top part a little to fit our shelve height?
Just finished the print. The lid handle is useless, tight fit of the lid means the handle should expand (reverse taper) or have some sort of ledge.
The lid has clearance so I might check your seam on this part! Otherwise I think a tight fit is good since it's in a moist environment :) I wrote down the idea with the taper! Good idea for a future V2
I like the tight fit... I plan to print and glue in a small fix that will give me something to grab on.
Hey! Awesome model. I noticed that the radius is not perfectly smooth, seems like a lower resolution STL export. Is it possible to get a higher resolution export, to avoid the visible triangulation in the rounded corners? Thanks!
Which parts of the archive have to be reprinted (I previously ordered the last version at the end of February)?
So first the inner assembly consisting of swirl, the stem and stopper. The bottom and insert stayed the same. You can reprint the top after trying it out to see if the additional radius in there is neccessary!
Hi there! I printed the model and it came out well. I have one question though, do I need to glue the container part to the stand? The fit is very loose and it makes the model quite wobbly. The lid, however fits perfectly tight.
There is no glue needed! If this is very loose there might be something off with the print but if it does fit together without leakage everything's fine!
I printed all parts with reduced infill (%12 and %10 depends on parts) and cubic type of infill, nothing else changed remains same.
After I printed it detergent flows just few (let's say 2/5 of cup) and then it just stuck there and doesn't move anymore, I re-printed the moving part in case there was an issue but same issue still.
Here is the example unlisted video: https://www.youtube.com/watch?v=KbGBC0XJav4
Hey thanks for the video, the swirl is plugged in, right? Did you secure it with glue? Otherwise what's the type of detergent that you are using? To make the trouble shooting easier, feel free to join so the discord so I can have a closer look!
I will join Discord and share more details soon.
