I like yogurt, especially these from locale cheese dairy. These yogurts are always filled in fine plastic cups. There are already many great ideas out here what we can make with empty yogurt cups.

I like to present you instructable in how to make a screw storage and recycle yogurt cups. Watch the following video to get an impression about my idea. (There are English captions because I speak German.)

Step 1: What Do You Need for This Project?

To be clear, my instruction involves a 3d-printer. If you don't have one, feel free to grab just my idea and make your storage with a different material.

Empty yogurt cups
Your 3D-Printer
Magnets (if you have a magnetic surface to attach them)
Dimension: 20x4x3mm

Screws (if you like to screw it to the wall)
Something to store in your new storage

Step 2: Adjust the CAD-Model to Your Cup Size

Depending on the country you live, the diameter of the rim from your yogurt cup will vary.

The *.stl file for a cup with a rim diameter of 73mm you find attached to this instructable.

Fusion 360 file for screw mount: http://a360.co/2qIAuSQ

Fusion 360 file for magnetic mount: http://a360.co/2qIFXZR

It is easy to adjust the CAD-file to the rim dimension you need. You just have to open it in Fusion 360 and adjust the one parameter. Every geometry will adjust itself depending on the new dimension.

If you have trouble with adjusting the CAD to your needs don't hesitate to write me a comment with the diameter you need.

Step 3: Print the Cup Holder on Your 3D-Printer

Now you can print your cup holder.

As I explained in the video, the design os optimized to print it tilted on the chamfer by 30°. This allows you to print it without any support material.
