Description

This design features a compartment to store Keurik K-Cups beside your machine. The cups are completely out of sight and fall into the drawer one by one. Pull out the drawer to get a cup, push it back in and another cup will be available on the next pull. The only non-3D printed parts for this assembly are some optional magnets to keep the unit attached to the Keurig. The front token can easily be redesigned to add a personal touch. It fits about 16 cups, I used the cups from Costco but it should fit any standard Keurig cup.

Note: The internal parts of the mechanism will differ slightly then what you see on the photos as I adjusted some angles and combined two parts into one. These are improvements over the original design (pictured) to help have fewer jams.

I recommend alternating the orientation of the cups when putting them in. You can fit a few more cups and it jams a lot less. With the new design, I am confident it will jam less than 2% of the time. If it does jam, simply push the drawer back in and pull it back out, it should solve the problem.

I've included the CAD files if you wish to adjust anything. If you print it, please share a photo, I would love to see it!

Let me know if you have any question.

***Update 2024-04-27*** Based on feedback from others, I have increased the width of the compartment and drawer by 3mm to help avoid jams. Some pods are prone to “pressurize” and expand making them taller which can cause them to get stuck. The height of your pods should remain at no more than 48mm for this to work well. If they are taller than that, consider increasing the width of the design some more. CAD files are included.

Awesome design. I will say the parameters are a little tight. I also use Costco K-Cups but sometimes they come pressurized and the foil top pushes out above the rim. When this happens they wont slide through this mechanism. Choices are to put a pin hole in the k-cup or widen that gap in the model or by increasing the size ever so slightly. One question I did have and maybe I am just missing it. The part that is labeled "Riser" where is this supposed to be installed? Thank you again for a really neat design.

Hi thank you for the feedback! I am not sure I understand your description of the problem, the K-Cups themselves get pressurized? Because they get squished by the mechanism on the way out? The Riser part might solve your problem. The space for one cup drawer is 55mm deep and 55mm high because some cups have a 53mm diameter (2mm of clearance). But the Costco ones are a bit smaller (50mm) which was causing the cup that is next in line to drop into the drawer area on top of the cup that is being pulled out. That caused the cup that is second in line to snag on the edge of the "tower" when the drawer was pulled. The Riser part goes at the bottom of the drawer to make the cup in the drawer sit a little higher to prevent the next cup to get caught in the mechanism when pulling the drawer.

i understand what you mean now, someone else posted with the same issue on Reddit. By how much do you think I should increase the width internally? I'll do some tests tomorrow and adjust the model.

Replying to @user90488 :

I think 3mm will be sufficient to fix the issue with the pods. I plan on printing a second one and can verify when I do. I just measured the pods and one where the foil top is perfectly flat is about 45mm and the other where the foil is pushing up do to air pressure in the pod is measuring right around 48mm. I measured 10 pods and got a + or - .1 mm on the grouping overall. Thanks for adjusting the model to accommodate.

Love the look of it. Is there a way to easily see remaining supply? If not perhaps if there was a viewing slot to see when you get to the last 5 or something similar?

The designer has replied

@user90488

The current design does not have any viewing slots as I wanted it to be as clean looking as possible. You can tell when there's 5 or less remaining from the feeling of the pull (it will feel a little lighter). if you wish to add a viewing slot you can modify the fusion 360 file I included to add one. vertically on the piece called "tower" would work well for that purpose.

@user90488

i forgot to include the magnet size. I used 6mm diameter magnets with a 2mm depth. You can easily edit the hole size and dpeth in Fusion360 with the included files. i usually go 0.2mm bigger than my magnets for the hole size and it gives a nice press fit.
