Description

Maybe you have seen all those electrical portafilter cleaner in the gastronomy sector. Thy work nice but also costs a lot of money. I designed this mechanical portafilter cleaning device which is fully 3D printed and doesn't need any additional hardware.

Functionality:

The cleaninghead features a 4:1 planetary gearbox. For every rotation of the portafilter, the cleaning Head rotates 4 times in the opposite direction.
So just put your portafilter onto the device and give it a few pushes back and forth. It should be clean enough for your next espresso.

Printing:

Everything can be printed without supports.
The "Rotation Tower" and the "planetary_gearbox" features print in place mechanics with tight tolerances. So you have to make sure that your filament is well tuned, otherwise the parts will bond together.

Sometimes it can happen that they stick just a little bit. For this purpose you can print out the provided "breakfree_tool" to loosen the parts or if you have a 15mm and 8mm Imbus you can try these. Never try to loosen the Rotation Tower Axle on the 8mm hex shaft inside, it could break!

The "Portafilter_Insert" and the "cleaner" must be printed in TPU.

Assembly:

Assembly is straight forward like shown in the picture.

Additional:

The Portafilter Insert and the Cleaning Head are designed for 54mm Portafilters like the one for the gastroback. You can try if it fits yours but I can't guarantee.
For those which doesn't fit I included the Step files with the crucial dimensions for the cleaner (cleaner_RAW.stp) and the Insert (portafilter_insert_RAW.stp) where you can design around these to get it right for your portafilter. The main device should be big enough to adapt it for even the biggest one out there.

Disclaimer:

The cleaning head is printed in TPU. There are a few varieties of TPU which includes some additives for better 3D printing experience. As TPU is generally food save, the additives might not. So check your filament to be sure!

Updates:

2024-12-12: added Brush Adapter:

For those wich still use a knock off box and want to use the cleaner just for cleaning, you can change the cleaning head with the brush - adapter. It can be printed in TPU or PETG. The TPU Version is softer but way stronger when it comes to wear resistance. But the bristles in TPU can be challenging to print nicely. The harder the TPU the better!

2024-12-14: Loose Clearances

Since a few people had problems with the clearances on the PiP - Parts, I updated the profile with two alternative plates with more clearances.

Clever :) Out of curiosity I printed this machine. Sadly my portafilter doesn't have wings xD But I will try a little around and maybe I get it working. Mechanism works fine. Printed the core parts on my Prusas and the bigger parts with my Bambulabs. SO I really did need the breaking off tool. Maybe increase the tolerances of the Rotation Tower by default. They don't need to be that "tight" ,-) Only thing I changed in your settings was to set the wall generator to Arachne. Have fun!

@laisch

Thx 👍 Looks nice. Yes it's always hard for PiP parts to find the right tolerances which will work for most of the users. I put the step files with the critical dimensions for the adapter and the insert here, maybe you find a way to get it working for your portafilter 😉

Replying to @laisch :

yah I will give it a try. But since my TPU's (soft medium hard, tpe, ..) have not that much surface friction. So my expectations are low xD But If I get it to work I can upload that specific parts to your profiles ;_) Normally I use my prusa printers for parts with tighter tolerances. But with the bambu slicer you can also make use of the slicer to "widen" only the x/y contour sizes. You could give that a try!

@laisch

Replying to @MeisterEdel :

Ah, ok so there is nothing to grab onto? just wondering how it connects to the coffeemachine? But if so, maybe you can try something like an inversed ratchet wheel (see picture). I think with the right angles and the inner diameter a little bit undersized it should grab onto the filter with enough friction. With the tolerances I always try to get it right in the cad file. Scaling afterwards in the slicer will work for axles, but for more complex geometries it could have negative effects because it won't change the gaps evenly. But what i found out so far, it depends a lot on the filament itself. With most of my standard PLA rolls I get clearances for PiP-Parts down to 0.13mm gaps. So 0.2mm like on the standard profile should work for most people. But then I have one roll of PLA Tough (white) where it even bonds on clearances over 0.25mm. It only helps to manually change the filament parameters to underextrude. Lidar Calibration on my X1C doesn't seem to work right with this filament. Often the seam position can be a problem on PiP parts bonding. That's why I put a small gap in the geometry, where the slicer should align the seam

Awesome model, I remixed the insert and Cleaner so it will clean a 18g VST (58mm) basket for my Gaggia Classic Pro.

Small update I glued in the planetary gears and then added some PTFE lube to those and the adapter and it now spins/works a lot easier. FYI I uploaded the print profile for my 58mm version for anyone else to use

I love it! The TPU isn’t pretty but it works.

The designer has replied

@laisch

Thx! Sometimes on thin TPU prints it helps if you switch to silent mode (=reduce the print speed to 50%).

@seggi_rm

Nice! However, I have a 58mm portafilter and wanted to edit the insert and cleaner. Unfortunately I can't find the step file you mentioned

The designer has replied

@laisch

;)

@seggi_rm

Thanks! I didn't realize I had to go to Makerworld and searched for the file via Bambu Studio and it didn't show up there

@duerlis

Would you like to share the 58mm version if it works for you? :)

I have a question is it also possible to clean a double shot cup ?

The designer has replied

@laisch

The standard cleaning head is just for single shot, because I had just this portafilter for designing. The brush should work also for double shot. But I also added the parts with he critical dimensions as step file for adapting it to yours.

thanks I Will try to make it myself

I hope it will work made it last night i’m not that good with fusion360 and takes time

I need to modify the "Plate 5 - TPU_Portafilter_Insert", could you change it?

(Edited)

The designer has replied

@laisch

Hi, you can find the step file for adapting to your filter in the raw files for download. 😉

@Hellcony

I love the idea, i've been looking for something like this for a long time! Unfortunately, the parts in the rotation tower won't separate. I printed it on both the A1 and the P1S, even tried with outer walls first - no success. I modified the break tool for a 1/2" ratchet and printed it in ABS. You can see the result in the photo.

The designer has replied

@laisch

Hi, sorry to hear that. Since another user had this problem on the gears I updated the print profile with two more plates where the gearbox and the rotationTower have more clearance between the parts. The original version has a 0.2mm gap and the new version has a 0,26mm gap between the parts.

I have seen a request here for a 58mm version. To which you replied the step files are included. But the TPU_Portafilter_Insert & TPU_Cleaner STEP files are not included. Can you please provide these so a 58mm remix can be made of these parts. Thanks in advance :)

The designer has replied

@laisch

Hi, I can upload them when I'm at home. But for adapting to your needs you have to remove the the non fitting geometry anyways, so that's why I just uploaded the "...raw" step with the special geometry already removed 😉

@Username32

Thanks 😊

Replying to @laisch :

Thanks for uploading :) Its very useful to have yours for critical dimensions. I will upload the print profile once I have it all printed and working.

Harsh, but a 51-piece cleaner option instead of 54 would be fantastic

The designer has replied

Show original

@laisch

Thx. the problem is, that I have no 51mm one where I can take measurements. But I added the step files for the adapter and the cleaning head with the crucial dimensions in the raw files, so everybody can workaround to get it to fit to their portafilter.

Replying to @laisch :

Thanks @laisch will give some findings if I can work a bit during the next days ;)

@Rucky

Replying to @oxmhitu :

I would be also interested into a 51 mm version as my attempts with FreeCAD were a bit unsuccessful. Coffee Maker is a De Longhi La Specialista Arte.
